Hi Luc,

My memory falls short on when we updated pherd.jar, however I think it was not changed since a very long time, far before we put it on git, therefore I have no idea on what causes the error with "official" 0.4.2 version ...

However, this same pherd.jar is used in 1.x, so the problem may still appear.

Does this error appears each time ?

It would be very helpful to have a way to reproduce the error, do you have some code chunk that produces it ?

Hi Luc,

There is no more support for 0.4.2. We now put all our efforts on the
1.x releases so support is dedicated to these 1.x releases.

Check new 1.1 release at   :

Hi GS team,

I'm still using GS 0.4.2. When I replaced by local JAR by the "official 0.4.2" release, I got the following error:

Exception in thread "GraphStream layout thread" java.lang.AssertionError: Particle in two boxes at a time ?
   at org.miv.pherd.Particle.setBox(
   at org.miv.pherd.ParticleBox.removeAllParticles(
   at org.miv.pherd.ntree.Cell.resize(
   at org.miv.pherd.ntree.NTree.checkDivisions(
   at org.miv.pherd.ParticleBox.step(
   at org.miv.graphstream.algorithm.layout2.elasticbox.ElasticBox.compute(

I'm simply trying to display a 10x10 grid. This worked perfectly with my previous jar (dunno where I got it).

Any idea?
