Bug 323892

Description Tuukka Mustonen 2010-08-28 18:15:55 EDT

Steps to reproduce:
1. Install Eclipse Helios (build 20100617-1415). Install Graphiti nightly build (0.7.0.v20100827-0726). Install JPA Diagram Editor (0.5.0.201008131407).
2. Create new JPA project. Select "minimal JPA 1.0 configuration". Use any configuration for library includes etc.
3. Open JPA Diagram via Project Explorer
4. Diagram opens without error, however, workspace .log contains the following trace:
