[jsr-314-open] [AjaxBehaviorEventAttribute] why must it be a literal?

[Ed Burns]

Hello team,

Mojarra impl issue 1143 asserts there is a use case for which allowing
the value of the "event" attribute of <f:ajax> (and thus for all
behaviors) to be a ValueExpression, at least in the case of composite
components.

I suspect there's a good reason why we chose to force the value of the
event attribute to be literal, likely security.  However, I want to know
why so I can close this bug in an informed manner, or challenge our
decision and possibly broaden the allowable value type for the
attribute.

Can someone please enlighten me?

Sincerely,

Ed
