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.

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.

AndyWhitley

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

Andy,

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

AndyWhitley

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

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.

rscheitlin

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

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.

AndyWhitley

Yeah it is weird, trying to download 4.1 now

rscheitlin

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

Grabbing it now, thanks for all your help.

rscheitlin

Andy,

Grab it from here:

AndyWhitley

I only see if 3.6, 4.5 and 4.5.1 sdk versions under complier, how can I roll back to 4.1?

rscheitlin

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.

AndyWhitley

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

rscheitlin

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?

AndyWhitley

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

rscheitlin

Andy,

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

AndyWhitley

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

rscheitlin

Andy,

That warning is insignificant and can be ignored.
