Re: [Repast-interest] Display problems with subcontexts

You should be able to set the data loader just on the top context. That context builder should create the two subcontexts and add the agents, projections to them. I’m guessing that the double displays is because the there are two copies of the networks and so they are displayed twice. Its hard to say for sure though.

So I removed them there, defined them in each of the subcontexts, and added my context builder to the DataLoader field in each subtree. Now I get my displays...but I get two of each! That is, I define one display in each of two subcontexts, and none in the top context, but I end up with four displays. Thoughts?
