How to reRender if Validation was OK

[razwed4ik]

Hi,

<h:form id="form">
......
a4j:commandLink action="#{bean.save}" value="#{msg['button.save']}" reRender="anotherForm"/>
......
</h:form>

as you see I have a FORM with a SAVE BUTTON. This button reRender another Form ad save this form in the Bean. My Problem is I want to reRender only if the Validation was OK, if not it shouldnt be reRender. Is this possible, maybe with JS.


Thx i A.

1. reRender allows the EL
2. the action method is invoked only if validation is ok

So,
add rerenderId as a property to the bean
say reRender="#{bean.rerenderId}"
let rerenderId is initiated with empty string
set rerenderId to "anotherForm" in your bean.save method

P.S. no js is required here.
