We are seeing some strange issues related to triggering submits/singleSubmits/partialSubmits with the keyboard/enter key.

1. Using compat component-showcase, open the panelCollapsible demo in FF browser. Collapse/expand a panel using mouse, all good. Now, tab focus onto one of the panelCollapsible header buttons, then use enter-key to toggle visibility. Submit goes off and never comes back (see busy indicator).

2. Enter key doesn't seem to properly submit/partialSubmit on some components.

2a. Using FF (or IE) again, try clicking on the "File" menuitem in the menuBar demo. Now use keyboard arrow keys to navigate focus ind. down to another menuitem, press enter to select it, nothing happens.

2b. Using the Calendar demo, click on the right arrow button beside the month on the inline calendar. Press Enter, Month changes in bean value, but not in the calendar itself. Pressing Enter again does nothing.

If you compare this behaviour to the icefaces/trunk showcase, you will see the differences clearly. Note that the public http://component-showcase.icefaces.org/ is running EE P02 code as a reference.

Could not reproduce these using WebKit browsers, but it is present on IEs and FF, strangely.
