      (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

          relates to

          Bug - A problem that impairs or prevents the functions of the product. TEIIDDES-2520 Teiid Connection Import fails when model name is set before model location

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
