I have a really strange issue with my dGrid that I was hoping someone could help with. I have an event handler where when I double click on a row, I display a Dijit dialog and make use of the grid row's ID property, make whatever updates I need, then click the OK button, which writes the changes back to a MySQL database via Dojo request.post. The OK button is using the on.once handler so it only runs once per double-click instance.
However, I've run into a situation where I noticed that some of the data in the grid was being duplicated/corrupted, and I've tracked it down when I double click on a row, and the dialog is displayed, then I hit Cancel, the on.once handler does not get cleared. So the next time that I open a dialog via the double click, I have an extra handler.
So my question is: how do I destroy an on handler that I no longer need?
Thanks,
Harry
