Error when switching from flash to webdynpro compiler

Hi,

Deploying a VC application in flash works fine, but when I change the compiler to webdynpro I get the following error:

The initial exception that caused the request to fail, was:



   com.sap.tc.wd4vc.intapi.info.exception.WD4VCRuntimeException: No parser configuration entry for the tag HtmlView

What do I have to change to make it work?
