Navigation Skin Error

AndyWhitley — Tue, 02 Aug 2011 13:34:20 GMT

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.

Andy,

That warning is insignificant and can be ignored.

When I go to export my release build it gets almost complete but then fails due to this warning?

Andy,

What Flex SDK version are you using and what AGS Flex API version are you using?

Re: Navigation Skin Error

I am using flash builder 4.5 and flexviewer build 2.3, hope this is what you needed.

Andy,

Nope... In Flash Builder right click on the FlexViewer 2.3 project (in the package Explorer) and choose properties.
Under Flex Compiler What is the Flex SDK Version you are using? Also under Flex Build Path and Library Path tab expand libs folder and which agslib-*-2011-*-*.swc are you using?

It displays 4.5.1....agslib is-2.31-2011-04-26.swc

Andy,

It is recommended that you use Flex SDK 4.1 with the old agslib-2.3.1-2011-04-26.swc and 2.3.1 version of the Flex Viewer.

Andy,

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

Re: Navigation Skin Error

AndyWhitley — Tue, 02 Aug 2011 14:54:10 GMT

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?

Re: Navigation Skin Error

AndyWhitley — Wed, 03 Aug 2011 12:29:40 GMT

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.

Re: Navigation Skin Error

RobertScheitlin__GISP — Wed, 03 Aug 2011 14:17:12 GMT

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.
