------------------------------------
Summary: Modeler: Exception when creating a new ObjEntity from
DbEntity
Key: CAY-2303
URL: https://issues.apache.org/jira/browse/CAY-2303
Project: Cayenne
Issue Type: Bug
Affects Versions: 4.0.M6
Environment: Nightly build of CayenneModeler:
Version: 4.0.M6-SNAPSHOT
Build Date: May 06 2017 07:40:32
Reporter: Andrus Adamchik
Assignee: Nikita Timofeev
Priority: Minor
1. Created new Model with 2 DataMaps (don't think 2 DataMaps is relevant here)
2. Created 2 DbEntities
3. Created a relationship between them, but forgot to specify joins
4. Clicked on "Create ObjEntity" button inside DbEntity editor.
5. The stack below appeared in a dialog.
I guess we can handle this condition more gracefully.
java.lang.IllegalArgumentException: No joins for relationship. Can't generate a
name
