If you have your converter tag inside a column then you get one converter for each column.

I guess you could save the tag's attibute string in the converter and do the value binding everytime getAsString() is called. Give it a try. It sounds slow but computers are fast and dynamic stuff is always more expensive. (Maybe create a new DynamicTruncateConverter :)
