I can't reproduce this in Ptolemy or Kepler on the Mac under Java 1.5.0_19.
What platform and version of Java are you running?
#2 Updated by Derik Barseghian almost 11 years ago
It looks like this bug is specific to the wrp suite; I don't get it in the kepler trunk or the workflow-run-manager module. Sorry about that.
I'm seeing it both on my mac: Java 1.5.0_16 and on linux: Java 1.5.0_13 when using the wrp suite.

I confirmed that this does not happen in the kepler suite. there might be something weird going on with the overrides in wrp or something.

there's a PTree override in the reporting module...but I don't see it being referenced in that module. Looking into removing the override.
