JPA Dali Eclipse Database Explorer EclipseLink

Generating entities using the JPA tool, I found that entities would not be generated for some tables. A workaround appears to be to go into the Database Explorer an expand the column listing for the table that is not showing its columns. When you go back to generating the entities you now find that the columns are listed and the table entity is generated. You can use the workaround in the database explorer multiple times before having to go back into the generation tool.
