In debugging a rather large application with GUI (written using Guide) all the sudden I'm getting:
Undefined function handle.
Error while evaluating uicontrol Callback
I'm not getting any indication of line number, just the error. There is somehting like 5000 lines of code so not easy to find where the issue is. In addition, turning on dbstop on error or dbstop on catch is having no effect. I also tried putting a breakpiont in the callback function for the radiogroup which generates the error when i click on it. No effect. Apparently the error happens before it gets the the GUI callback...? I am stumped as to how to proceed!

Turns out the radiobuttons somehow got disassociated with the uibutton group they were in. i had to delete and make new ones.
