Max Andersen commented on JBSEAM-843:
I got a patch for this now.
Currently it adds "generate-ui" as a task that uses jpaconfiguration to run view generation from compiled classes instead of the reverse engineered model. ant "generates-entities" still both do reverse engineering and generate-ui.
The advantages of this is that you now can actually refer to the entities classes while rendering the ui (needed for new-query functionallity)
The "downside" is that the generated code have to be compilable and be mapped correct/valid before the view can be generated.
Because of the above I haven't just comitted this to seam since I don't have the time to test if common combinations will work.
chicken-egg issues while doing this patch:
1) the hibernate/ejb3 libraries in seam seem to be "old" since they don't include the method from Ejb3Configuration to build a Configuration without creating a sessionfactory. (Workaround: include newer hibernate/annotations libs that does support it in seam-gen/lib)
2) to run a jpaconfiguration requires the code in the project to be compiled (Workaround: call from seam-gen to the project's "jar" task)
