Ok thx G, I add a improve ticket for that. I found a solution : on my initialize method of my class,I backup all ComponentMouseButtonListener and remove it from my TableViewHeader I add a new ComponentMouseButtonListener on my TableViewHeader and on each method (mouseDown, mouseUp, mouseClick) execute all backuped ComponentMouseButtonListener depend if the column is sortable or not.
It's not beautiful but that work.
