Description

When using the workbench application in some cases, a page fails to load and the following exception appears (usually on the second request). It seems to me this is likely a bug with the annotation support of the framework.

org.apache.hivemind.ApplicationRuntimeException
Error: An error occured processing annotation @org.apache.tapestry.annotations.Asset(value=images/tab-active-left.gif) of public abstract org.apache.tapestry.IAsset org.apache.tapestry.workbench.components.Border.getActiveLeft(): Asset activeLeft has already been declared (at Annotation @org.apache.tapestry.annotations.Asset(value=images/tab-active-left.gif) of public abstract org.apache.tapestry.IAsset org.apache.tapestry.workbench.components.Border.getActiveLeft()).
