Re: Re past 2.0 with terracotta?

Hi Mark,
You actually pointed out some interesting thing...
I converted this terracotta demo from Repast 1.2.0 to 2.0 beta, so I guess
some of the package structure has been changed? This could be a problem.

I spotted that in my repast.simphony.action.display_1.xml:
...
<projectionDescriptors>
  <entry>
    <string>Terracotta Grid</string>
    <repast.simphony.visualization.grid.GridProjectionDescriptor>
      <proj class="repast.score.impl.SGridImpl"
reference="../../../../projections/repast.score.impl.SGridImpl" />
      <entry>
...

I did a search on that class and its src, and I didn't find it in Repast 2.0
beta. I believed that's the problem. Can anyone tell me where to find this
grid implementation class in Repast 2.0? I'll report if this really IS the
problem.

Thank you guys very much

-Charlie-
