hi bart, that sounds strange. could you please debug the issue? first step: set a breakpoint at the first line of LengthMetaDataTransformer#convertMetaData and have a look what you get in as value of the metaDataEntry.
you should see something like: @org.apache.myfaces.extensions.validator.baseval.annotation.Length(minimum=3, maximum=7, ...) (and for sure something like $Proxy39) regards, gerhard http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2009/9/11 Bart Kummel <[email protected]> > Hi, > > I just added MyFaces ExtVal to my existing project, which uses MyFaces > core, Trinidad and Orchestra.
