[IDV #XES-933915]: query related to initDataSelctionComponents (more details)



Gansham & Don,

I am seeing multiple invocations of updateSelectionTab when loading a file via 
the data chooser. The repeated invocations of updateSelectionTab is because of 
the formation of the JTree in the Field Selector. Any time a node is added or 
the path of the tree changes, an event is fired leading to the invocation of 
updateSelectionTab.  See

DataTree.treeStructureChanged

Is this a problem? Should we refactor the code to invoke updateSelectionTab 
only after the JTree is complete?
