Ok, I followed a video by Doug Hull on basics for Tables in GUIDE: http://blogs.mathworks.com/pick/2008/05/07/matlab-basics-adding-a-table-to-a-gui/

and made the assumption that to set the data in a table you can do:

function Table_CellEditCallback(hObject, eventdata, handles)
info = [1 2 3;4 5 6];
set(hObject,'data',info);

and it worked...

I then added some complexity, I get some appdata and set it to be info and the set call broke. Apparently there is no 'data' property and I get the following:

Error using hg.figure/set The name 'data' is not an accessible property for an instance of class 'figure'.

I have rolled back the code to when it was working, restarted MATLAB and it's still broken. I have no idea why it has stopped working.

Help Please!

It means that the figure is calling this instead of the table. Thus hObject is the figure handle (the source calling the callback) instead of the table handle and that's why you're seeing the error.

To fix it, specify the handle to the table, something like:

set(handles.Table,'data',info)

Please feel free to leave an angry message for Doug too ;)
