[Seaside] Differentiate between onClick: and onDoubleClick:

[Squeaker]

Hello,

I am using Scriptaculous with Seaside.

I want to be able to do action1 when the user clicks on an item and 
action2 when the user doubleClicks on an item.

Here is what I am seeing: when I doubleclick on an item, the callback 
for onClick: gets called twice.

Is there some way to differentiate between click and doubleClick?

Many Thanks,
Frank
