      (02:50:28 PM) blafond: I'll need a stack trace to figure it out
      (02:50:35 PM) blafond: check Designer's Error Log view?
      (02:50:39 PM) asmigala: the weird thing is, it sometimes works for the same data source
      (02:50:42 PM) asmigala: ok, hang on a sec
      (02:50:53 PM) asmigala: so this is not something we know about?
      (02:51:34 PM) blafond: not as a reproduceable bug.

      (02:59:47 PM) asmigala: also, when I copy the DDL, save it to a file and then use the DDL importer, it works correctlu
      03:05:15 PM) blafond: I think it's a threading/timing issue. The RelationalReferenceFactory is assuming that the new EMF Model already created. Looks like it's still in the process "sometimes" and ends up failing.
      (03:05:45 PM) blafond: I noticed that we don't save the model right after we create it. Maybe that could fix the issue.
      (03:06:05 PM) blafond: Please log a JIRA/BZ and include all of this conversation
      (03:06:59 PM) asmigala: yes, that makes sense, I generally don't see it when stepping through the test
