Comment 2 Tomas Pavek 2013-09-10 16:31:12 UTC 
Caused accidentally in 7c190d9e604c by introducing new method parameters when one of them (propNames) now hides a field of the same name that was used so far, but now the parameter is used instead which is always null. (It's a shame there's no warning in java editor about this.) This makes the JPA-related components unusable, code generation always fails when there is any property set.

Fixed by making the field name different from the local parameter name, i.e. returning to previous correct behavior.

Comment 3 Tomas Pavek 2013-09-10 16:53:06 UTC 
Can be tested simply by adding e.g. the 'Query' component from palette (Java Persistence category) to a form, setting the query property to anything and then switching the form to Source - which invoke code generation. It fails before this fix.
