[jbdevstudio-users] Problem adding JPA facet to maven project

[jbdevstudio-users at lists.jboss.org]

Denis,

In answer to your question, I was going to send you the version of my previous installation It was a 7.0.0 Alpha build), but then I was able to reproduce the problem in 7.1.0.GA.

The original pom I tried had a parent pom.  Once I removed the parent, the facet-add worked.  Here is the pom that failed with NPE (logs to follow). well not the whole pom, just this section:

<parent>
    <groupId>gov.ssa.dne.nmst</groupId>
    <artifactId>dne-main</artifactId>
    <version>1.2.0</version>
  </parent>
<artifactId>test-2-jpa</artifactId>
  <version>0.0.1-SNAPSHOT</version>


When I changed the pom to this, the thing worked:

<groupId>gov.ssa.dne.nmst</groupId>
  <artifactId>test-2-jpa</artifactId>
  <version>0.0.1-SNAPSHOT</version>

And... here is all the version info:

Version: 7.1.0.GA (http://7.1.0.ga/)
Build id: GA-v20131208-0703-B592
Build date: 20131208-0703

Dali Java Persistence Tools - JPA Support
3.3.1.v201308261920-7V7_5FC7sRe5TdgZcI05646d

well, some of it.  Let me know what, if any more, you need.

And here is the full NPE stack trace. I tried it twice. I included both (probably redundant):
