That won't also work because there's a redundant dot before the bracket. ;)

Mark,

What isn't working... the binding?  What are you getting for your TextInput
text value with the suggestions from Oleg and myself.  You definitely
shouldn't be getting the same issue as you first posted about with these
updates, so where is it falling short now?

 thanks for the suggestion, Oleg, but that didn't solve my problem... any
 other ideas?

Why wouldn't you just do this:

TextInput text={myDataProvider.data.name[0]} /

 Actually, as I understand it, I am using ActionScript to create a variable,
 but I am then binding that to an mxml component, no?

 anyway, any ideas of how to do this?

 thanks!

  That would never have worked in Flex 3.
 
  You are trying to use a binding expression in ActionScript code which
 will never work. Binding expressions like that will only work in MXML code.

  9084-7d85.html . I have tried to implement this technique but have
   still been unable to get it to work.
  
   When I specify the following:
  
   [Bindable]
   public var
   collection:String={myDataProvider.data.name.[0]};
  
   I simply receive the following in my textInput field:
  
  
   {myDataProvider.data.name.[0]}
  
   Does anyone have any ideas as to how I might specify a bindable
 variable
   such that it will display as desired ?
  
   (FWIW, this worked like a charm in Flex 3)
  
  
   thanks!

Hi, I think square brackets may be an obstacle here. I think they didn't
always work, or maybe they don't work even now? Anyways, if that's an array
collection, you'd better use getItemAt() and if that's an XML or XMLList,
you'd be better of with the XML / XMLList methods corresponding to what you
wanted to do (like child(), children() and so on).
Also, data is often times used in the framework for instances of Object,
which is not bindable because it is not an IEvetnDispatcher. Check that
option too.

Re: [flexcoders] Re: textInput databinding

Mark, glad you got it worked out.

However, you need to look at the fact the Spark TextInput extends from
SkinnableTextBase which contains the properties you'd expect.

 Bingo! that did it!

 the final solution, in my example, is:

 text={myDataProvider.getItemAt(0).name}

 thanks for your help, Oleg, and to everyone who contributed to the
 conversation.

 best,
