Implementation of multiple combo boxes in uitable.

Hi all,
I am interesting in being able to integrate row-dependent combo-boxes into a uitable. The current version of uitable supports cells with combo-boxes but these have to be the same for a given column. Ideally this feature would be available via uitable, however it is not. So, I have been exploring the java route as proposed by Yair Altman (Undocumented Secrets of Matlab). This requires the use of a custom cell editor class. I have downloaded the version he provides that employs a hashtable to set up a series of different editable cells. However, when I try implementing this I find that the combo-boxes do not contain any entries. Some code is given below. Any advice most welcome, particularly if I am attempting something that can be more easily accomplished via another route. The .java and .class files for the custom cell editor ('LookupFieldCellEditor') can be downloaded from here (<http://undocumentedmatlab.com/files.LookupFieldCellEditor.zip)>. I have tried recompiling the java class via javac but to no avail.
Best wishes,
John
