For simplicity, I prefer to disable changing weights whenever any of the nodes in the current project uses a custom operator. Before, I was allowing to change weights in the single case in which the IRI node was using a custom operator, but not the others. I found a little bug in that solution, and anyway I prefer to keep things a little simpler.
There was also a case in which the map was not displayed, so I fixed it too.
