don't agree with u.
Be sure i do some tests (and some code reviews) before posting here
My test case is the following :
Show a grid, open the column menu, then destroy the grid : 23 DOM elements in sIEve
repeat twice : 46 elements in sIEve
repeat more : 69 elements ! and telling me re-used ? when ?
not releasing elements in my menu :
- 1 SPAN (x-menu-item-text) + 1 IMG (x-menu-item-icon) by Menu Item,
- some DIV and BUTTONS (pagingtoolbar) not released due to sus-mentioned memory leak
