[OPEN] [#649] When Tree selection is not set to TreeSelectionModel, node is selected when it's expanded
In 12/04/2014 i opened a thread related to node selection after its expansion http://forums.ext.net/showthread.php...-it-s-expanded.
In 14/01/2015 i confirmed that it has been fixed on version 3.1.
But at this time i found another issue regarding node expansion.
When TreePanel's SelecionModel is set to TreeSelectionModel (default), everything works as expected.
But when TreePanel's SelecionModel is set to CheckboxSelectionModel, RowSelectionModel or CellSelectionModel, the node is selected when it's expanded.
As mentioned on the related thread, it's possible to overcome this issue by overriding Ext.grid.NavigationModel.onCellClick, as shown below:
Note: It only fixes CheckboxSelectionModel and RowSelectionModel
