Actually, it is in the FeatureList widget. There is an initTargetModel
event that gets called. What's odd about it, is that it retrieves the
targetModel tag that I defined, but the executes a statement that does
something like this:
if(!objref.targetModel)
{
... some alert code...
targetModel = model;
}
What's odd about the above piece, is that when I debug at that if statement,
it has retrieved my targetModel and pulled it out of the config, but then it
goes ahead and overwrites it with the parent model. I think doing,
!someobject, was a way to test for null? If so, the object isn't null so I
don't know what it would fail. I'm really just kind of puzzled. I'm going
to look at the mergemodel tool and see if using some of that code might help
me.
