RE: [flexcoders] Re: mx:States and databinding issue

OK, I confirmed how binding basically applies to the SetProperty tag but
doesn't apply to the target of the SetProperty tag.  We've filed a bug
and will see what happens.

Glad you could get the workaround going.  I'll forward this into the
team and see if they have any thoughts.

Matt,

After a ton of debugging I finally was able to change the value of the
button in the State via actionscript and not through binding with the
SetProperty tag.

public function formsValid(...args:Array):Boolean
{
for(var i:int = 0; i < args.length; i++)
{
  if( args[i] == false )
      return false;                       
}
  parentDocument.addClientBtn.enabled = true;                       
  return true;
}                 

<mx:states>
<mx:State name="default" id="defaultCCView">
<mx:SetProperty target="{parentDocument.addClientBtn}" name="enabled"
value="{formsValid(personalDetails.formValid,contactDetails.formValid)
}"/>
<mx:SetEventHandler target="{parentDocument.addClientBtn}"
name="click" handler="submitClientForm()"/>
</mx:State>
</mx:states>


Now I'm not sure if this is a databinding issue with States and
SetProperty tag, but this workaround isn't something I'd like to do in
the future. I hope someone can point something wrong in my code that
would make the state handle the databind correctly, but I just don't
see anything wrong.

Thanks,
Sof
