Hi Seth, hi Marc, I guess Seth means the difference between v2.0.x and v2.1. To get the compatibility with ExtJS 5 we had to rewrite some parts of tree structure. One thing was to introduce a util-class which handles visibility of the layers according to the treenode's checked state (as Seth described). What I don't understand is the thing that all "param-layers" turn off whenever any of the nodes are unchecked. In the 'updateLayerVisibilityByNode' we just work on the selected node and its dependent layer. It should not be the case that other layers (besides base layers) are affected. As Marc already wrote: Is there any code we can see?
As short-term-solution you can either overwrite the 'updateLayerVisibilityByNode' function or you unbind it and bind your own 'checkchange'-handler.
