Hibernate DataSet with UserTypes

Moi

I create a Hibernate dataset and everything is fine, I can preview the data. If I add a column that is mapped using a UserType, in this case an enum, I get the following error :

Failed to prepare the following query for the data set type org.jboss.tools.birt.oda.dataSet
...
'foo.GenericEnumUserType' is not a valid type


The sad thing is that when I test the query, it is declared valid.

Has anyone achieved something similar?

Does it mean that hibernate support is minimal and should not be used?

Should I work with a Scripted DataSet instead?


Thanks for your time
