I have a treetable that is grouped into a hiererchy. The user has the option to change the name of one of the parent levels. How can I refresh the data in the treetable to reflect this name change and maintain the grouping?
I have tried and failed with:
treetable.clearAll();
treetable.load(xxx.php);
Strange thing is that if I force the php file to have just 1 line in it, that line appears as 1 row in the treetable. If I try 2 manually created rows, it fails ie. blank treetable.
