Found the solution. Apparently I never had any callbacks for the radio buttons associated with the ButtonGroup. So by simply adding the default Callback for each button the error went away. I did this in GUIDE by selecting each radio button and right clicking on each one then selecting the Callback submenu.

Recently upgraded to R2014b. I've been getting a brand new warning type error from Matlab from a GUI which was working before the upgrade. When I select a radio button from a radio button group I get:
Undefined function handle.
Error while evaluating UIControl Callback
Now this is doesn't prevent the code from working but is really annoying. The it only happens when I change buttons so I think it's probably associated with this piece of code.
function cutplane_SelectionChangeFcn(hObject, eventdata, handles)
% hObject handle to the selected object in cutplane
% eventdata structure with the following fields (see UIBUTTONGROUP)
% EventName: string 'SelectionChanged' (read only)
% OldValue: handle of the previously selected object or empty if none was selected
% NewValue: handle of the currently selected object
% handles structure with handles and user data (see GUIDATA)
switch get(eventdata.NewValue,'Tag')
case 'rcut'
handles.cuttype='r1d';
case 'thetacut'
handles.cuttype='theta1d';
case 'zetacut'
handles.cuttype='zeta1d';
case 'fluxcut'
handles.cuttype='r2';
case 'polcut'
handles.cuttype='theta2';
case 'rzcut'
handles.cuttype='zeta2';
case 'threedcut'
handles.cuttype='3D';
end
guidata(hObject,handles);
guiupdate(hObject,handles);
Now I see that this should probably be SelectionChangedFcn rather than SelectonChangeFcn but when I make this change then basically the propery of the fig isn't correct for the GUI.
Any thoughts?
