How to change the visibility of sub-tpk layers without effecting the whole tpk

Discussion created by teamigal on Apr 2, 2013
Alright, this is going to be a bit hard to explain.

I have edited the MapLayerTemplate and LayerTemplate of the Legend with a visibility checkbox:

It works great on my MPK, but not on my TPK.

My TPL shows in the legend with "sub layers", but when you try to check any checkbox, they are all binded to the same value and change simultaneously.

Is this normal behavior?
