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? -IDV Support > Here is some info on the initDataSelectionComponents/updateSelectionTab > calls. > > > -------- Original Message -------- > Subject: Re: query related to initDataSelctionComponents (more details) > Date: Tue, 01 May 2012 13:59:44 +0530 > From: Ghansham Sangar <address@hidden> > To: address@hidden > > On 05/01/2012 01:07 AM, Don Murray wrote: > > If you could do a stack trace on where it gets called from each time, > > that would help diagnose the problem. > > > > Don > > > > On 4/28/12 6:20 AM, Ghansham Sangar wrote: > >> hi Sir > >> > >> Any idea why when open a datasource (I mean a file), > >> initDataSelectionComponents in datasource class gets called up more than > >> a few times?
