Mouse events are not properly handled [message #1220107]

Hi,

There seems to be a problem with the handling of mouse events. Hard to explain so here are some steps to reproduce the issue:

Open Examples
Goto the Group By Example
Select the first value in the ISIN column
Press control
Move the mouse down to item 9
Click again with the left mouse button to select them.
WITHOUT MOVING THE MOUSE: Do a right click.
Nothing happens, but the context menu should appear

It is very critical to NOT move the mouse, otherwise the issue is not reproducable. If you move the mouse everything works fine Smile

I debugged into it and it seems that - due to some event - the wrong IModeEventHandler is set. The new handler now does not know anything about opening the context menu and thus nothing happens.

Seems that the bad line is in:

MouseModeEventHandler#mouseMove:

// No drag mode registered when mouseMove detected. Switch back to normal mode.
switchMode(Mode.NORMAL_MODE);

For me it seems that this overwrites the handler that would open the popup menu.

Regards,
Michael

The problem is that the mode is not reset after selection via mouseDown.

I'm testing a possible solution.
