When trying to close my gui which contains a plot of several graphs, I encountered an error (below). This error repeated continuously (infinite loop of error) and I wanted to know how can I avoid it.

Here is my close request function:

function figure1_CloseRequestFcn(hObject, eventdata, handles)
AllMyTimers = timerfind('Tag', 'myTimers');
if ~isempty(AllMyTimers)
     stop( AllMyTimers );
     delete(AllMyTimers);
end
delete(hObject); % this is where the crash occures (2688 in figure1_CloseRequestFcn )

------ The error: -----

Warning: Too many objects created while deleting uipanel children; removing DeleteFcn of all descendants to prevent infinite loop.
> In MainGUI>figure1_CloseRequestFcn at 2688
  In gui_mainfcn at 96
  In MainGUI at 33
  In @(hObject,eventdata)MainGUI('figure1_CloseRequestFcn',hObject,eventdata,guidata(hObject))
{Warning: Too many objects created while deleting uipanel children;
removing DeleteFcn of all descendants to prevent infinite loop}
> In MainGUI>figure1_CloseRequestFcn at 2688
  In gui_mainfcn at 96
  In MainGUI at 33
  In @(hObject,eventdata)MainGUI('figure1_CloseRequestFcn',hObject,eventdata,guidata(hObject))
{Warning: Too many objects created while deleting uipanel children;
removing DeleteFcn of all descendants to prevent infinite loop} 
...

and so on, infinitely.

Hi, Was this problem solved. I too encountered a similar behavior and am looking for ways to solve it.

@Dhanya: This thread could be solved, because Shahar did not show the code (although "I've added my figure1_CloseRequestFcn" seems to imply this). Without seeing the code, how could we suggest an improvement? So please open a new thread and add the details.
