    "The backend currently does not support this feature." when

    ajordens Newbie

      I've just done a first pass at migrating an existing application from 3.2.7 to 4.0.1.

      Has anyone ran in to the "The backend currently does not support this feature." when running 4.0.1 against PostgreSQL 7.4.X.

      I haven't made any changes to the jar file beyond re-compiling, is there some place someone can point me. I'll continue to search through the forums, a google search didn't reveal much other than a bug report with the same problem.

      Exception trace has been included below, any questions? Thanks in advance.
