Re: [flexcoders] LinkBar ViewStack Problem

[Clint Tredway]

This is a creation issue. Basically, the input text field is not 'created' yet. You have a couple of options. The simplest, is just bind the text of the input to the value you want to store there.<mx:TextInput text={
list.selectedItem.somevalue}"/>There are other options, but that should get you going.On 10/17/06, Daniel <

            Hello all!

I've been having this particular problem, I have 2 canvas inside a
viewStack, lest say something like:

<mx:ViewStack id="viewStack" width="100%" height="100%">
     <mx:Canvas id="list" label="List">
          <mx:DataGrid doubleClickEnabled="true"		                   
              doubleClick="viewStack.selectedIndex = 1;
              input.text="list.selectedItem.someValue">
	  </mx:DataGrid>
     </mx:Canvas>
     <mx:Canvas id="form" label="Form">
          <mx:TextInput id="input"/>
     </mx:Canvas>
</mx:ViewStack>

Its simple, but whenever I double-click on the DataGrid, Flex gives an
error saying that it can't access a null object (referring to the
textinput "input" that is defined inside the second Canvas and is hidden).

I've noticed that when one uses viewstacks or accordions and wants to
access to an object inside a container that is hidden to initialize
it, there is no way to access it. 

I've tried selecting the canvas first and then assinging the data,
like I did in the code above, but doesn't work either.

I really need help with this, otherwise Im gonna have to change the
layout of the hall application.

Thanks in advance!
