Description Ivo Bek 2013-11-25 13:51:12 UTC

Created attachment 828685 [details]
screenshot with the NPE

Description of problem:

I just click on build&deploy for a project where I didn't make any changes. It asks me whether I want to save my project. I confirm that yes and a dialog (attached screenshot) containing NPE will appear.

In the server log is just a part of that NPE:

14:46:02,535 ERROR [stderr] (Thread-115) Exception in thread "Thread-115" java.lang.NullPointerException
14:46:02,535 ERROR [stderr] (Thread-115) 	at org.uberfire.metadata.io.BatchIndex$1.run(BatchIndex.java:57)

there is nothing more

Comment 1 Ivo Bek 2013-11-25 13:56:56 UTC

I should also mention that the first time I saved the project before build&deploy, the exception had been different. I wanted to create another BZ for that but it seems it's the same problem.

Comment 2 manstis 2013-11-25 14:12:44 UTC

This issue is definately caused by you having an out of data repository clone. When kie-commons and Uberfire were merged (https://bugzilla.redhat.com/show_bug.cgi?id=1018535) the meta-data namespaces changed. 

You will need to delete your local .niogit and re-clone. If you are using "internal QE" repositories it is likely they contain out-of-date meta-data and need to be refreshed from github.

See comments 1 and 2. Do you have a up-to-date repository clone? I cannot replicate this issue with the current uf-playground repository.

Comment 5 Ivo Bek 2013-11-25 14:42:47 UTC

Thank you, after I changed our internal repository .project.imports to use org.uberfire.java.nio.base.Properties instead, everything works as expected.
