Description Gunnar Wagenknecht

Usually, when you migrate a project you do it step-by-step. When generating entities from an existing schema this approach is not supported by Daily because relations are only resolved against new tabled in the generation scope.

Existing entities in the project should be recognized, too, when generating new entities from existing tables. This would better fit an incremental development/migration approach. Relations would be resolved against existing entities and as a benifit the existing entities would get new fields/methods, too, if a new relation to an already existing entity is detected.

This makes more sense now that we have reworked the wizard to allow the user to preview the Entity names. Previously it did not make sense, since the generation of Entity names is not entirely deterministic.

We need to move some code from GenTable to GenerateEntitiesWizardPage so that name collisions are handled and displayed to the user. We also need to prevent the user from entering duplicate entity names.

Sounds great. :)

Investigate for 2.0.

It's not looking like this will make the 2.0 release, since we haven't managed to investigate further at this point, and it is a non-trivial enhancement.  Setting to future to be evaluated for 3.0.

Moving JPA specific bugs to new JPA component in bugzilla.
