Seam-gen generate-entities does not work for tables with composite key
----------------------------------------------------------------------

                 Key: JBSEAM-3977
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3977
             Project: Seam
          Issue Type: Bug
          Components: Tools
    Affects Versions: 2.1.1.GA
         Environment: DB2
            Reporter: Julien Kronegg

Generating entities with seam-gen produce an error when the table specified in the seam-gen.reveng.xml file has a composite key:

    freemarker.core.InvalidReferenceException: Expression property.value.identifierGeneratorStrategy is undefined on line 2, column 75 in pojo/GetPropertyAnnotation.ftl

This is because the composite key has null identifier, see https://jira.jboss.org/jira/browse/JBSEAM-562
We've found references for that problem in
  http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4013107
and in
  http://opensource.atlassian.com/projects/hibernate/browse/HBX-1004

Interestingly, we could not reproduce the problem using Seam 2.0.0.GA.

One method to correct that issue is to guard the expression in *.ftl files by something like: property.value.identifierGeneratorStrategy?exists
However, since Seam 2.0.0.GA .ftl files do not have such guards, it must be another way to correct the problem
