Updating Grid from Controller

Feb 23, 2011 at 6:27 PM

I have a grid that displays appointments for specific people as a gantt chart.  The user can modify the appointment data by double clicking the cells (each cell is a day of the week).  I am capturing the double click with a controller attached to the specific appointment cells.  Inside the controller I am displaying a dialog form where they can edit the info.  My problem is I am trying to update the grid by deleting cells and adding modifications from within the controller.  This gives me an error inside the ControllerContainer that a collection was modified.  How can I have the grid updated without generating this error?  Is there an event loop I can post to from inside the controller?
