Navigation Skin Error

[AndyWhitley]

I get the following warning when trying to save my flash project:

Data binding will not be able to detect assignments to "Length".  NavigationSkin.mxml

I am new to Flex, any suggestions would be greatly appreciated.

Grabbing it now, thanks for all your help.

Andy,

   Strange thing is I just built the Flex Viewer 2.3.1 project using Flex SDK 4.5 with no warnings at all...

[AndyWhitley]

Yeah it is weird, trying to download 4.1 now

Robert,

I downloaded 4.1 and the error went away however now when I hit run on my viewer it never opens up.  Any more suggestions?  I switched sdk back to 4.5.1 and even 4.5 and the warning returns.

Andy,

  Those are some strange issues. So first question is why are you using the 2.3.1 instead of 2.4? Have you looked in the problems window to see if there is anything else going on?

[AndyWhitley]

I don't see anymore issues displayed in the problem window.  I have been using the 2.3.1 version for a few months since I am new to Flex.

Robert, also do you know where I can download a Live Layer Widget?  I want to refresh a point map service within my viewer.

Andy,

   The QueryWidget replaced the old LiveLayerWidget form the old Sample Flex Viewer.

Thanks, I will check that out.  I am still researching the navigation skin warning.

Andy,

Not sure where "Length" is declared in your code nor how is it being used, but when I get this error, I always check to ensure any variable with this error is bindable, simply by inserting

[Bindable] public or   private   var   variableName:  DataType;

in AS4 section of my code.
