Errors in Flexviewer using API 2.0

ShaningYu — Tue, 31 Aug 2010 18:56:52 GMT

I used ERSI's Flexviewer template and like it very well. Several months ago, I tried to use API 2.0 to replace 1.3. However, I got a lot of errors. Today I tried again, and was still unsuccessful. A typical type of error is post below:

component UniqueValueInfo is defined more than once in this namespace. Remove the mapping to com.esri.ags.renderers.supportClasses:UniqueValueInfo or com.esri.ags.renderers:UniqueValueInfo
Resource: Flexviewer
Location: Unknown
Type: Flex Problem

I had a post below for this problem. Has any accounted this problem? If yes, how to solve it? Please share your experience.

Thanks.

The UniqueValueInfo class has been moved to the com.esri.ags.renderers.supportClasses package.

http://help.arcgis.com/en/webapi/flex/apiref/index.html?com/esri/ags/renderers/supportClasses/UniqueValueInfo.html&com/esri/ags/renderers/supportClasses/class-list.html

This is currently missing from the migration steps, but we'll add it there.

Also make sure you don't have the old swc in your libs or Project Settings.

The errors display after I removed API 1.3 and added API 2.0.
Per your response, ESRI has not fix this defect in its API yet. Is it right? Thanks.

Using the Sample Flex Viewer with the 2.0 API is not supported. It could be done, but it'd be a lot of work since you'd also be moving to Flex 4. You could start with the 2.0 beta of the ArcGIS Viewer for Flex available at: http://help.arcgis.com/en/webapps/flexviewer/

It should be possible to migrate non "Sample Flex Viewer" apps to 2.0 relatively easily depending on their size.

Make sure you only have the 2.5 swc in the libs folder or referenced in the project settings under Flex Build Path -> Library path.
