I'm using a custom tabbar with the dataProvider being a viewstack and I'm trying to get the tab labels to update when data in the related container (in the viewstack) updates. The viewstack's containers are bound to bindable vars, so if a var changes, the data/labels/etc in the container updates, but the tab doesn't.Is there a way to bind the tab to the same bindable var or do i need to write event handlers (if so, what events)?
View 1 RepliesI have a situation where I need to update a DropDownList's dataProvider and selectedItem in a specific order. See the following code ...
<s:DropDownList id="dropDownList"
dataProvider="{someDataProvider}"
selectedItem="{someSelectedItem}" />
In my case, some user interaction produces new values for the bindable variables "someDataProvider", and "someSelectedItem". However, when flex renders the DropDownList, the control's selected value is empty.
The reason for this is that the DropDownList's "selectedItem" property gets bound before the "dataProvider" property. The "dataProvider" needs to be bound first for "selectedItem" to be valid, this is because the new "selectedItem" points into the new "dataProvider".
what is the best practice for updating bindable properties in a specific order? I've come up with a few ways (e.g. using a valueCommit handler), but I wanted to see what the community had to say.
Is it possible to have the value of some string variable bound to the text inside a text input control? To clarify, whatever text was entered into the text input would be stored as the value of the variable.

Is it possible to specify MXML-esque "binding strings" in ActionScript?For example, I want to be able to do something like:
MXMLBinding(this, "first_item",

I love MXML but am starting to notice some of its drawbacks. The main one I'm struggling with is its larger memory usage due to the need for binding. In the super simple code snippet below, which I've tested on Flex 4.0[code]...
My main question: is there any way to set variables in MXML that doesn't eat up memory? I'm aware that I can do this explicitly in AS and keep MXML as a bare bone structure but was wondering if there was an alternative path.
Secondary question: why memory usage in c different from a and b? I've looked up at the intermediate code and it seems like the const case still sets up some binding logic but not as much and have been wondering why that is.
This animation I'm working on has a dozen pairs of movie clips (with only two library items, one for each type in the pair) with instance names of the form "x" and "xgoal" (this is a drag and drop thing).When I'm writing AS for the "x" clip, how can I refer to its "xgoal" generally? I tried something like:goalName = this._name + "goal";And then using the goalName variable in my dot syntax (retrieving the _x coordinate for the goal clip):this.xgoal = _root.goalName._x;But, of course, that did not work. How can I get around this?
View 1 Repliesload multiple variables from a single text document into one main dynamic text field. If it is possible could someone post an example for me i would appreciate it a lot
View 6 RepliesI am using a for loop with "i" as a counter. I have some dynamic text fields (name0_txt, name1_txt, name2_txt...etc.) in a mc called namesList_mc and some variables being returned from php called name0, name1, name2 etc.Where and how do I then use "i" to avoid writing the same code hundreds of times.
namesList_mc.name0_txt.text = variables.name0;
namesList_mc.name1_txt.text = variables.name1;
namesList_mc.name2_txt.text = variables.name2;
..etc.
When I open a text document containing 1 string of a Base64 Encoded Image, it works fine:
ActionScript Code:
import flash.display.Loader;
import flash.utils.ByteArray;
[code]...
The image displays and that's great, but I need to display multiple images; therefore, I used the standard format: var1=value1&var2=value2&... (In reality, the values are the huge base64 strings.) Then I just needed to add "my_loader.dataFormat = URLLoaderDataFormat.VARIABLES;" since the format of my source changed. The thing that bugs me is that I'm tracing the imgB64Str after I set it and it traces fine (just like the other version).
ActionScript Code:
import flash.display.Loader;
import flash.utils.ByteArray;
[code]...
It runs with no errors, but the image no longer displays.
I have 25 dynamic text fields. If I could, I'd just assign their text by calling the array in the text property var, but that doesn't work.My text field variables are simply B1, B2, B3, B4, B5, I1, I2, I3, I4. . . (I'm populating a bingo card)I'm using 5 Arrays to get the 25 numbers. bArray, iArray. . . and so on.Now, obviously I can fill in my text fields by assigning each variable separately, however, I'd like a shorter solution.Instead of coding B1=bArray[0], B2 =bArray[1] I was looking for a way to assign all the variables in a for loop... or something...

I am at work right now trying to create a power point for our Christmas party. I know I can do so much more with Flash than I can with any other power point program. Right now, I'm trying to figure out a way to load a list of names into one dynamic text field that changes at certain time intervals. I'm using ActionScript 2 right now b/c I haven't learned 3, yet. Is there a way for Flash to access a word document and load a name say, every minute? I know I could add a different variable name in front of each employee name, like content, content1, content2, but I have a list of like 300 names here. That would take up almost as much time as it would creating a slide for each name in Power Point.

I'm new to Actionscript programming. I'm trying to figure out what is the best way to return multiple variables, each having a different data type, from a function. For example, if a function needs to return variable aa ( a string) and variable bb (a number).
The function I'm using just crunches a lot of math, and doesn't relate to an object in a GUI. One method I got from a Google search used an Object, but as (I think) this requires me to create a class, I wondered if there was a simpler way. Since an array can hold elements of different data types, perhaps this is a simpler approach (?). [code]...
I have a series of images loaded in via XML and assigned to "loady" movieclips. This code works fine:

_root.myMCL.loadClip(_root.myImages[2].attributes.url,_root.loady2);
_root.myMCL.loadClip(_root.myImages[3].attributes.url,_root.loady3);

I want to replace this with a loop since I know the total amount of items (myImagesNo), but this isn't working:
Code:
for (i=0; i<_root.myImagesNo; i++) {
_root.myMCL.loadClip(_root.myImages[i].attributes.url,this["_root.loady" + i]);
}

View 1 RepliesI did suppress warnings in flex compiler using "-show-binding-warnings=false". But what I am interested to achieve is to suppress run time warnings (especially binding warnings - since I am getting data in model mostly in XML structures and it is fine for me if its unable to bind to its nested child nodes) in console (I am working on flex on Eclipse with the flex plug in). Is there a way to achieve it?

I have a datagrid that gets its data from a webservice.When data from the webservice is retrived it calls the following function:
private function onListReg():void
{
arrRegOld = WSAutoreg.list.lastResult as ArrayCollection;
arrReg = WSAutoreg.list.lastResult as ArrayCollection;
[code].....
The intent is when I hit a update button, it compares arrRegOld with arrReg and see if any values have changes. The problem is whenever I change values on the Datagrid it changes on both the dataProvider and on both ArrayCollections.What should I do so that the binding applies only to one ArrayCollection?
I'm having some troubles with binding data. I have an application that contains a viewstack of components. Let's say I have comp1, comp2 and comp3 inside the viewstack. Each component, has its own data class --> comp1Data.as, comp2Data.as and comp3Data.as. All values in each component are binded to the corresponding data in it's data object.
A click in a control in comp1 leads to comp3, the same goes for comp2. Clicking a control in comp2 leads to comp3. When going from comp1 to comp3, comp3Data.as is initialized and and comp3 displays the binded values. When going from comp2 to comp3, comp3Data.as is also initialized but the binded values are not displayed...

I am using flex SDK 3.5. I have model.as and in it i have an ArrayCollection (name it arr_mod) which is Bindable.
From my mxml i link to this arr_mod in three places:
1) in DataGrid i set dataprovider={arr_mode} ...
2) in Button i add new item to the arr_mod this way: mx:Button .. click = "{arr_mod.addItem(new Item)}"
3) in textBox i want to add mx:TextBox text="{mySpecialCounterFunc(arr_mod)}"
note that in the Script of mxml arr_mod is Bindable as well as in the class definition in model.as
The problem is, that when clicking on button, mySpecialCounterFunc is not called! it should be called, since i use {} and this should listen to changes in arr_mod (a change that was made in the button should cause a new item to be added.. and than the listener to respond). While The DataGrid is updated correctly! By the way, if i change arr_mod to simple String or Int it works.. i.e. mySpecialCounterFunc is called Why??
