I want my JavaFX program to be able to dynamically change the accelerator for menu items. However, I cannot get it to work in JavaFX 2.2. In the code below, in the first menu item there is an accelerator "Ctrl + M", and it works fine. "Ctrl + M" is printed every time a menu item is selected with the mouse or with the keyboard accelerator Ctrl + M. The second menu item tries to change the first accelerator of the item for people to "Ctrl + L". Having selected the second menu item, I can click on the first menu item again and it shows that its new accelerator is “Ctrl + L”, but I cannot use the keyboard accelerator Ctrl + L to activate the first menu item. Instead, I still need to use Ctrl + M to activate the first menu item. Any suggestions on what's going wrong here?
