RE: [argouml-dev] Persistence problem with my macmas module

Title: Message

Bob would be the best person to know whether there have been any changes to the PGML parser in GEF (which ArgoUML uses) which would trigger this type of behavior, but the first thing that you should do is to be ABSOLUTELY sure that your class is packaged the way that you are expecting and is available on the Java classpath.  The fact that it works in one environment and not the other makes me suspicious that this is a packaging issue.

Subject: [argouml-dev] Persistence problem with my macmas module

Hello all

The first stable release of MaCMAS implementation project is nearly to appears. Unfortunately, we obtain an error that not appears in previous development releases.

I'm totally surprised with this problem because when I run the project from eclipse all works fine but if I use a compiled version of ArgoUML and MaCMAS module it produces the error below.

There was a suspicious problem in eclipse with my project: when I try to generate from eclipse a serial ID for the MACMASTraceabilityDiagram classes and other MaCMAS diagram classes, eclipse blocks and not produces a serial UID. It doesn't happens with other classes such as figures, panels, etc. I suspect that this can be the reason of the persistence fail of loading the PGML.

The sequence to obtain the error is the following:
- run a compiled version ArgoUML vPRE-0.22.2 (our module is a little coupled with this version of argo)
- create a new diagram of our MaCMAS module and create several elements in it
- save the project
- restarts argouml and open the project saved and it produced the exception showed below

Please help me. Thanks.
Francisco Gonzalez
