Java Null Pointer when using Merge Columns

[Elijah Meeks]

The only thing different about this graph is that it has a datetime MySQL field imported.

I imported the edge list and stripped out everything but SOURCE, TARGET and ID (and only ID for nodes) and still get the same problem.

Yes, sorry, a image path was changed by mistake in a recent update.
But it was fixed in this http://bazaar.launchpad.net/~gephi.team/gephi/0.8/revision/2104 revision and an update should be available soon.
