Re: [Solved] ajax4jsf trouble after a form has failed JSF
validation
One other thing... it occurred to me that I could probably bypass any
complications from JSF validation by adding immediate="true" to the
"a4j:support" tag. The method did fire when I did this, but the elements
defined in "rerender" did not refresh. I'm sure the solution is in here
somewhere, but I'm just not seeing it.

Re: [Solved] ajax4jsf trouble after a form has failed JSF
validation
Posted by raindogs <co...@yahoo.com>.
I just tried it with t:messages with forceSpan="true". No luck there either.
I also ran an a4j:log and, surprisingly, it looks almost identical before
and after the failed validation. Despite the fact that the method does not
appear to fire (I used Eclipse to watch for a breakpoint), it is actually
getting the values and the Ajax log shows it updating the appropriate
elements. Unfortunately, the elements displayed on the screen remain the
same. It seems like the AJAX stuff is all working and that JSF is just
refusing to cooperate.
This is incredibly puzzling and frustrating. I am now moving past the
"careful debugging" phase and into the "curse at the screen, pound on the
walls, and frighten my co-workers" phase.

How about trying t:messages with forceSpan="true"

Thanks for the response. I did put the <a4j:outputPanel ajaxRendered="true">
around the h:message tags, but the problem persists. I also tried adding the
t:saveState to the values in the drop-down, but that didn't work either.
I also posted this to the Ajax4Jsf forum on the JBoss site, but anyone here
who can think of another way around this will immediately earn a spot on my
Christmas card list.

Re: [Solved] ajax4jsf trouble after a form has failed JSF validation
Posted by Adrian Mitev <ad...@googlemail.com>.
The h:message/h:messages component is not rendering anything if there is no
error message and that's why it cannot be rerendered if there is an error
message (this is the most possible reason for your action method not to be
invoked).
Nest the h:message tag into <a4j:outputPanel ajaxRendered="true"> like this:
<a4j:outputPanel ajaxRendered="true">
<h:message for="addressName" />
</a4j:outputPanel>

Re: [Solved] ajax4jsf trouble after a form has failed JSF validation
Posted by Si...@equifax.com.
I too had this problem, in my case the managed bean was in request scope.
I did a t:saveState on the select item list and it solved the problem.

Re: [Solved] ajax4jsf trouble after a form has failed JSF validation
Raindog,
