[CLOSED] RowEditor and RowExpander do not work properly together
There is a Grid that contains a RowEditor and RowExpander.
When the RowExpander is present, the RowEditor does not function, and an error is thrown: "Cannot read property 'lockedGrid' of undefined".
A previously used sample code below:
I am also getting the following error "Cannot read property 'apply' of undefined" when the Grid is loaded.
When the RowExpander is removed, there are no more errors and the Grid and RowEditor work perfectly.

grid.editingPlugin.locked = true;
