In Flex Builder 3, I am trying to access the main applications view state from within a component.On initialize I show the Loginpage-component. When I click the login button I want to hide the loginpage and show my "controlpanel" page, which also is a component.I try with this, and also placing this function in the main application.[code]
View 1 RepliesFollowing is a simplified version of my mxml:
[Code]...
"A term is undefined and has no properties..." which points me to the line this.parent.currentState='edit'.
I am learning Flex and trying to make a simple RPG to practice. I am using view states to change between screens. right now I have a HomeView.mxml which displays my character information, InventoryView.mxml which shows my inventory items, and EquipmentView.mxml which shows the equipped items. They each have their respective view states.
in my main mxml file, i create a global variable for the character and an ArrayCollection of items in the game. it creates 2 labels in mxml for Inventory and Equipment and when i click on the label it calls a click handler which sets currentState="EquipmentView" or "InventoryView" This works and the state changes and the respective views are shown properly. My problem is in my EquipmentView state. When i enter the state the first time, it has a creationComplete function which displays images for my equipment and sets a click handler. when i click the item, it "unequips" it and removes it from the equipment list and removes the image. this also works fine, but when I go to my inventory view and "equip" an item and return to the EquipmentView, the image does not show. I have a label which counts the length of my equipmentList variable and that is accurate when i switch views, but i cant get the image to display again. Is there a way to call my displayEquippedItems() function (which is originally called on creationComplete) when the view is changed?

I have decided to go the route of using ViewNavigator and having one view with 3 states. Each state is a "page". It runs just fine on the desktop but when compiled for mobile, the transitions between the pages is really laggy, even for the Samsung Galaxy S. The phone has the 2.7 runtime and I recompiled my application with ADT 2.7, still no performance increase.
I have also tried cacheAsBitmapMatrix on all 3 pages, which are all contained in a VBox and that hasn't shown any significant performance bumps. All I'm changing is the y component of the VBox for each transition.
EDIT: I have done some more research and I am now to the point where I have hardware acceleration turned on and cacheAsBitmap = true and cacheAsBitmapMatrix = new Matrix(). I am also using Stats.as to see the FPS. I notice on my state changes I go from 25 FPS to 2 and then it goes back up again.
I have one list, which the item render it`s like this:link. But now I need to enable or disable the button delete depends the view state which my List is inside. This is my view(which contains the list):

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
my problem is when i create a button in state 1 and click on it according to code it should make a group in another state named as expand. However according to my code it is still making group in current state 1.

I currently use: Flexglobals.toplevelapplication.component1.compnent2.currentState = 'something';is there a better way of doing do? Can I bind the state of a components to variable in my model?
View 2 RepliesI have a Flex component that is a view of a data Object that recursively has a reference to itself.
For example if you had an Employee class that references a boss field of type Person, I'd like to nest the same view for that Boss. This shouldn't be an infinite recursive relationship (e.g. I'd only be viewing the boss field of each object).
I've tried creating an MXML component that references itself but when I run it locks up (seems like it gets into a recursive loop).
Is there anything you can do like includeInLayout conditions that will make sure it doesn't even instantiate that component.
I have lots of child text inputs within a spark Scroller. How can I make the TextInput with id of "x" come into focus if I have a..z id's, also for the scrollbar to scroll automatically to that child item? I can use x.setFocus(), but the scrollbar doesn't automatically scroll to that item? why?
<s:Scroller id="scroller" width="100%" height="100">
<s:Group id="group" width="100%" height="100" id="content">
<s:TextInput id="a" text="" editable="true" width="100%" height="25" />
<s:TextInput id="b" text="" editable="true" width="100%" height="25" />
....
</s:Group>

I'm experiencing some strange text rendering behavior in the Spark RichEditableText component.
<?xml version="1.0" encoding="utf-8"?>
<s:Application
xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
[Code] .....
The above application simply navigates through the five sentences in the DATA array (every time the Next button is pressed). For whatever reason, RichEditableText component doesn't completely reset its view (by clearing the previous text) before setting new content. From what I can gather, this faulty rendering is somehow based on the combination of line count and relative width. I also discovered that if I set the width property of the RichEditableText component to an absolute value (say, 100) as opposed to relative (percentage, 100%) the text is rendered correctly. As far as I can see, this behavior is unintended and is, in fact, a bug.
I'm currently building a Flex 4.5 mobile project including several views and custom written MXML components that can be incorporated dynamically into those views.How do I determine which component currently has focus, namely has been activated by the user tapping on it? The background for this is a global search function in the main application. Depending on the results of this search, fields in the custom components are set. Given that I don't want all components in a view to listen to the outcome of that search function, I have to check which one is currently active.I'm trying to bind the selected object (the result from the search function) to the active component.
View 1 RepliesI don't know if this is too difficult or too easy. My custom component is trying to listen to the main application's state changes using StateChangeEvent.CURRENT_STATE_CHANGE, but it's reporting its own state changes.
View 2 RepliesI have flexlib WindowShade component in repeater in my Flex + AIR application.
<mx:XML id="mainMenuXML"><items>
<item value="abc" />
<item value="xyz" />
<item value="lmn" />
</items></mx:XML>
Now in button1 click handler I am appending child in XML(mainMenuXML) resulting adding one more windowshade instance. But the problem is it opens all the windowshade instances. I need to maintain the opened states after adding a new windowshade instance.
For example:
Initially I get 3 windoshades with labels: abc, xyz, lmn all opened.
Now I close the xyz windowshade instance(by clicking on the header)
Now I click on button which appends child in mainMenuXML and also add a windowshade instance with some label "pqr". But now I see all the windowshade instances opened.
But it should be like abc, lmn, pqr should be opened & xyz closed(property opened="false").
How to maintain the opened true/false state of windowshade instances. I tried to add a property in dataprovider Bindable to opened property of windhowshade but didn't worked for me.
I have a custom class that extends the Tree component so I can add some logic to the drag and drop functionality and not allow folders to be dropped inside folders.In the dragOver function, I am using:

to determine the drop target, and setting:

Do you know how if you drag an <mx:Label> or <s:Label> component into your Flex project, when you go to design mode you get this panel on the right to set its properties like text etc.
I have a custom component that I can call with actionscript, or with mxml like this:
<comps:TheComp field1="OK" field2="Yes" />
The component takes this input and uses it for its internal operation
[Code]...
When I go to design mode, I can see the component under custom components, I can drag it to the stage and see it, but can't set its values field1 and field visually on the right like a normal <s:Label> or <mx:Label> would have. how I can add that? Do I need to make it inherit something or anything else
I've made a custom list itemRenderer with 2 buttons and a label. One button deletes the list entry (and thats not the problem) the second button would change the actual view.how I can change actual view within the itemrenderer ?
View 1 RepliesI've used JRab's example here [URL]... to add a header menu to my app. What I'm having trouble with is executing my functions from the header mennu. For example, my firstView is appHome.mxml. It instantiates a Canvas object that has an erase(). There is a button in appHope.mxml that executes the erase() on the Canvas instance. I'm trying move the Erase button out of my appHome.mxml and into my headerMenu.mxml but don't know how to execute the erase() on the Canvas instance. The first thing I thought to try was click="{appHome.myCanvas.erase()}" but obviously that didn't work.
I asked a similar question yesterday here: Flex executing a function on another view and I accepted the answer before I tried it. The problem is that the headermenu.mxml is not a child of appHome.mxml. They are both children of the main app.mxml. Secondly, the object that has the erase() is in a separate .as class I instantiate in appHome.mxml.
Does there exist a Flex view component that you could just pass it a custom object with all public fields/properties that it could reflect over and produce a basic UI view using flex components. Is it possible to use something like the Spark DataGrid with one item laid out vertically. It would only have to support:

I am a beginner developer in Flex, and I have been using viewstates lately. I had a couple of custom popup titlewindow components that are initialized using[code]...
They both contain view states already, and are very similar so I wanted to combione them into one popup titlewindow and change view state on initialisation of the popup to either the Create version of the popup or the Update.
I thought I was being smart haha, but I realized soon after refactoring my code that, I as far as I know I can't pass parameters to the popup to indicate which state I want, if it is created using the PopUpManager.
Does anyone know how to pass parameters to the PopupManager, or create the ContentCreate component(TitleWindow) in mxml or code so I can specify the view state?
when I try to loop through the children of a List component that has buttons in it, I can't seem to access those children. I try

use namespace mx_internal;

enter code hereI am loading an external swf into an component. It loads everything fine and I can see buttons working in the swf, I can add a movieclip to the but I can't then access that movieclip (or don't know how), and it keeps telling me numChildren = null when I try to trace it out. This is set up as a custom component like this:
<cynergy:imageZoom
id="zoomComponent"
borderStyle="solid"
source="{_data.map.@url}"
[code]....
how I would access the children in the loaded movieclip?I have tried
mycomponent.image.getChildAt(2) and it returns and error that the index is out of bounds.
I need to be able to call a method from a component located under the main application in Flex 4. Can anyone tell me please how to do this without using FlexGlobals please?[code]

View 2 RepliesI'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.
View 1 RepliesIt's my understanding that view states can be useful when switching the layout of design elements. Such as, a loading page as one state and the main application design in another state. Is this the correct use of them? Additionally, I have a label in State1 and I cannot figure out how to access that label via actionscript. labelID.text = "New Text"; is not working.
View 2 RepliesI'm using Flex 4.5 and trying to take advantage of the new state groups feature. I have two States (call them readType1 and readType2) that both belong to the same stateGroup (call it readOnly). There are several places where I'd like to do something based on the current state, and it would be the same thing for the two read states. [code]...
