    TreeGrid issue with SmartGWT v12.1p_2020-07-31/PowerEdition Deployment (built 2020-07-31)

    We recently updated our apps to use smartGWT version v12.1p_2020-07-31/PowerEdition Deployment (built 2020-07-31). Most of the features seem to be fine and did not require code change.
    But in one of the tree grids in our project we noticed that when we expand a node in the tree grid's data, the grid doesn't open the node instead adds a duplicate node into the grid.
    This issue got introduced in the new smartGWT version only. If we switch back to previous version SNAPSHOT_v12.1d_2020-02-21/PowerEdition Deployment (built 2020-02-21) , the tree grid behaves as expected without any code change. With the older build of smartGWT we can successfully open the nodes in the tree grid's data.

    Can you please let me know if this is a know issue with the new build?

    Not a known issue (we basically fix all known issues immediately - we are not a "WONTFIX" type of company).

    What this sounds like is possibly that, when a DSRequest is made for the children of a node via load on demand, a copy of the parent is erroneously returned in the data. This would have undefined consequences, and undefined behavior can change between releases.
