Table & Converter = " unsorted column ?"

Hi amigos.
My problem is this:
i have a IndeexedContainer that holds objects, so for not to see something like MyClass@1cd26d9 in the row, i addi converter to hte table column.

table.setConverter(“myColumnName”, new MyConverter());

but after this i cannot sort that column for hom i addid converters.

Please help me with advice how to do the sorting and have converters.
