Hi, I created a menuItem with an Acceleator

      
fileSaveItem = new MenuItem(fileMenu, SWT.PUSH);
fileSaveItem.setText("&Save\tF11");
fileSaveItem.setAccelerator(SWT.F11);


When I run the application I get 

java.lang.IllegalArgumentException: Empty key sequence definition found

However, when I do :
      
fileSaveItem = new MenuItem(fileMenu, SWT.PUSH);
fileSaveItem.setText("&Save\tALT+T");
fileSaveItem.setAccelerator(SWT.ALT + 'T');

it works. Is this a bug or intended? (I use RAP 2.2)

Hi.

I guess it's a bug. If it works in SWT, it should work in RAP.
You could open a bugzilla report where this can be discussed.

Greetings,
Tim
