Right. Moreover, you're using a BaseLayerContainer, so only base
layers with displayInLayerSwitcher set to true should appear in the
tree.

You can add a breakpoint into LayerLoader.js where the filter is
applied (function addLayerNode) and see what's going.

For further assistance here could you please come up with a small
example (a map panel + a measure tool + a tree panel) demonstrating
the issue.

Sorry for not being more helpful here.
