NPE in Indigo SR2 when adding JPA facet [message #814538]

I've been running Indigo SR1 with Dali (for JPA support) for some time without issue.

Today I'm trying a fresh install of Indigo SR2 from scratch. When I go to add the JPA facet to my Java project, I keep getting a NullPointerException as follows:

Any help on this is welcome as our team has really grown to depend on the Dali tools for JPA!

I'm not seeing this behavior. Can you give more details for how it occurs, preferably in a new bug?

Not to distract from the bug you are probably entering, but did you use the "Configure" menu "Convert to JPA Project...", or some other mechanism? I assume your existing projects are importing fine?

This seems to be working for me as well. Happy to hear your team is experiencing the benefits of the Dali tooling. Hopefully we can find a quick resolution to the problem you are seeing.
