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.

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

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!

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?

2010-07-15 Thread Oleg Sivokon 
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.

Brendan,

I've tried this every which way I can imagine... variable assignment within 
quotes, without quotes, within and without braces, and with and without dot 
notation before item selection.

Going back to the beginning, I'm wondering if there might be another way to get 
the value I want into a variable. Specifically, I'm wondering if I can bind the 
value I want to some other type variable and then copy/change/cast it to a 
String variable.

Any other ideas/suggestions?

thanks, Mark

Brendan,

Actually, that's where I started, as it worked in Flex 3. The only properties 
of Spark TextInput are:

 s:TextInput
Properties
widthInChars=Calculated default
  



the properties of Halo TextInput are:

mx:TextInput
Properties
condenseWhite=false|true
data=undefined
displayAsPassword=false|true
editable=true|false
horizontalScrollPosition=0
htmlText=
imeMode=null
length=0
listData=null
maxChars=0
restrict=null
selectionBeginIndex=0
selectionEndIndex=0
text=
textHeight=0
textWidth=0



... quite a change, huh!?

the final solution, in my example, is:

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.
