java - invalid range exception with setAutoCreateRowSorter() -

i getting invalid range exception jtable when use setautocreaterowsorter(). if remove setautocreaterowsorter, problem goes away, no longer able sort table. also, if try setting sorter directly:

mytable.setrowsorter(new tablerowsorter(model)); 

i still same error.

this close sscce think can convey issue.

the problem occurs when click checkbox on table. close sscce think can convey issue. if take away sorter, problem not persist.

this part sticks out me:

at mytesttable$mytestabstracttablemodel.setvalueat(mytesttable.java:151) 

this post closest thing can find similar problem, not answered. how implement table sorter without receiving error?
