uitable is very very buggy, especially when it was first introduced (I think R2008b). Which version of MATLAB are you using?

When I try to save the state of the gui using saveas, I get a bunch of "could not serialize object" warnings related to the uitable. Ok, I can deal with that (just need to recreate the table after opening the saved .fig file).

However, (after using saveas) every time the gui needs to redraw, I get the java exceptions listed below, usually about a hundred times in a row, basically making the gui unusable. (Though if i open the saved version and recreate the table, it works fine.) Any ideas why using saveas would break the table? I wouldnt expect saveas to make any permanent changes to the figure, but that's what seems to be happening.
