So, I've created a sample application that utilizes a TreeByNestingTableColumn. I can open/close nodes within the tree structure, and all looks well, until I try to select a row after expanding at least one node. When I select a node, the entire expanded tree structure collapses, and trying to re-expand the tree node leads to an IllegalArgumentException.
What am I missing?
I followed the sample tutorial for NW 7.01, as described [here|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/bc/601c420d84db2ce10000000a1550b0/content.htm]:
