Hello,
It appears that neither indexOf() or findIndex() methods work when the Tree is loaded from a DataSource. find() works just fine. The issue was observed using Chrome 39.0.2171.99 and Isomorphic SmartClient/SmartGWT Framework (v10.0p_2014-12-09/Enterprise Deployment 2014-12-09) in both development and compiled modes.
Test case:
1. BuiltinDS.java
2. test_tree.ds.xml:
3. test tree table:
Start the application and click "Check" button. find() method correctly returns a TreeNode that can't be later located by indexOf() nor findIndex(). Both calls return -1.
