Martin Funk updated WICKET-480:
-------------------------------
Attachment: diff.txt
So how about something like this?
Support events that are compatible in all browsers and also allow developers to
add javascript to events that they demand for explicitly.
Btw, what's a well recogniced resource on compatability issues between the
different browsers? As you have seen I currntly can come up with quirksmode and
wikipedia.
