Andrew Robinson commented on TRINIDAD-1906:
-------------------------------------------
I would vote that this is not a bug, and should not be fixed for Trinidad 2.
f:ajax is a JSF tag, not a Trinidad tag and we should not have to support it
with respect to client validation in JSF 2.0 for the following reasons.
I would say that we should wait for JSF 2.1 where, hopefully, the EG puts in
API hooks to allow users to perform client side validation during a JSF ajax
request. It was commented for JSF 2.0 that such a hook should exist and the EG
dropped the ball on it and it was not included into the spec.
A work around is to use the Trinidad APIs to submit the request. I would say
that we could provide a tr:ajax that would be supported or we could hijack the
f:ajax tag handler, although I would hesitate to do that as it would make
Trinidad not "play nice" with other JSF libraries.
I do not feel that replacing the JSF request function is a good choice as we
ought not to be messing with the JSF internal code if we can possibly help it.

> <tr:panelFormLayout>
> <tr:inputText id="ajax" label="Field 1:">
> <f:ajax event="change" />
> </tr:inputText>
