TreeGrid editing confusion

[drakator]

I have added
TreeGrid.addRowEditorExitHandler (new RowEditorExitHandler()
{
public void onRowEditorExit (RowEditorExitEvent ev)
{ ...

on my overwriten TreeGrid, but the editor is not closing now.
even if I call TreeGrid.cancelEditing () or TreeGrid.endEditing ()

The RowEditorExitEvent does not work in my code.


also I have a code like this:
TreeGrid.getTree().add (nodeBook, root);
TreeGrid.selectRecord (nodeBook);
TreeGrid.openRecordEditor (nodeBook);

and the openRecordEditor replies with:
(TypeError): type: undefined_method arguments:
getNodeDataSource,[Tree ID:isc_OID_71]



I spend all my day trying to figure out what is happening with no result.
is there an example of TreeGrid editing where I could use as tootorial?

Editing via a "recordEditor" (the openRecordEditor API) is an experimental feature unrelated to normal inline editing, which is controlled by setCanEdit(true). With normal inline editing the rowEditorExit event show fire, post a standalone test case if you aren't seeing this.
