Ilya Shaikovsky commented on RF-4222:
-------------------------------------
any supports count should works for the component. This seems not nessesarry.
If somebody will provide the case where it is not works - we will investigate
and fix this.
> Nice to have multiple events in a4j:support tag

> in the a4j:support tag, it is now possible enter an event for which you want
> to occur something (e.g. reRender):
> <a4j:support event="onblur" reRender="usernameDecorate"/>
> Sometimes it would be very userful if reRenders occur for multiple events.
> For example there are two events in which you are interesed: onblur and
> onkeyup.
> The onblur should check where a username containts valid characters (by using
> a regexp)
> The onkeyup should display the current length of the username (in an
> <h:outputText />)
> So, based on above example it would me nice if the support tag supported
> (hehe) more than one event).
> For example: <a4j:support event="onblur,onkeyup"
> reRender="usernameDecorate"/>
> I already tried to create a separate a4j:support for each event, but then
> only the first one is executed.
