Layer Transparency for LiveMapsWidget in Flex 2.2

JamesKo — Fri, 14 Jan 2011 14:48:19 GMT

What happened to the Layer Transparency option in the LiveMaps Widget in the Flex 2.2 Viewer?

In version 1.3, users were able to change the transparency for each layer...any help would be appreciated.

James,

I guess you are taking about the layerListWidget in 2.2...? Well anyway the transparency slider thing was overlooked for some reason. I did create a TOC and legend widget that has an opacity slider for all map services.

Robert,

I'm having trouble getting this widget to work. It compiles without problems but I'm getting an error message at line 292: function getFeatureResult, filterOutSubLayer (Error #1009: Cannot access a property or method of a null object reference.)

Any ideas?

fyi, I'm using the uncompiled version.

James,

what does your TOCWidget.xml look like?

James,

Do you have layers in your main config.xml that are type="feature" and are pointing to a non 10 server?

Robert,

That was it! I had one layer of type "feature" pointing to an incorrect service.

Thank you very much for your time.

James
