i put a scrollableDataTable inside a modalPanel. When i click a column header and attempt to sort the table all the column headers suddenly disappear. Also a column more than needed. is added to the table (this from the start not as a consequence of sorting) I can post a screenshot with the code next monday if it can help. For the moment i switched to a datascroller but that's not exactly the same and it's not what the client asked. Where did i go wrong?
