I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
View 4 RepliesI have a mxml component with a datagrid listing project names and code versions. I have the selected projects from the datagrid binded to a public variable named "selectedProjects". But how to access this variable in another mxml component. I want the selected project's name in that component's text area. I even created an instance of the first component and using that called the selectedProjects variable. But I do not get the value updated in the text area.
This is the code for the first component where I get the selected projects name in a variable:

I've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?

I am actually in the process of Architectural of our project. We have choosen Mate framework. The project is not so quite complex, but what advantages i would get over MXML when i choose Modules.
Main App - > Views - > Events - > Maps - > Services [PHP or Java]
When i come up with Modules based Architecture, it seems to be good but i doubt it should not end up with tight coupling and unwanted issues which may break the head later to solve.

What advantages i do get if i choose Modules over MXML Component? What is the prefered and the best way to Architect an FlexApplication? Since the Application is going to communicate with Backend, do we need to make the frontend more complex?
In our flex application we have tabs at the main level and under it we have subview.e.g
Home / Tasks / Admin etc...
In one condition we have to click on a button and open a new tab, on this tab we have to add an existing mxml component and show it in the tab.We are using parsley as the framework. Inside the mxml component test.mxml(that is shown in the tab) i am configuring it with parsley using the tag.Now when i add the instance of this test.mxml i am getting an exception. I am deriving this test.mxml instance using teh parsley context
as
context.getObject(id of component) as DisplayObject and adding it to the tabNavigator...
But i am getting exception when i try to grab an instance of a view using parsley context. How do i get an instance of a view or component that is configure through parsley using the parslye context.Also the problem is occuring becuase of the view injection..because i get a parsley excepiton on startup of the application stating that there is some problem in the context.
i want to implement this.archive/flex/tourdeflex/web/#docIndex=1;illustIndex=0;sampleId=0)type of structure in my application.how can i display different component in differentparts.

View 1 RepliesI'm using several custom MXML components in my Flex 4.5 application.They all use absolute coordinates to place Image, Label, Line, etc. components and are currently based on a spark.components.BorderContainer:
<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer
xmlns:fx="http://ns.adobe.com/mxml/2009" [code]....
Then I've realized, that I probably don't have to use BorderContainer, because I don't draw/need any borders around my custom components.But I don't know, what to take instead of it.I've tried taking <mx:UIComponent> (and removing <s:Layout> tag above), but then I get the error:
'Image' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.
'Label' declaration must be contained within the <Declarations> tag since it does not implement 'mx.core.IUIComponent'.
Is there some simplest possible spark "container"? And do I need a "container" at all if I use (and want to use) absolute coordinates?
I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.
