How to execute a4j:commandLink oncomplete only when validation has succeed?

jsf-2, richfaces, validation

Solution

RichFaces supports request based EL evaluation in `oncomplete` attribute. So you should be able to print `FacesContext#isValidationFailed()` as if it's a JS condition.

For example,

oncomplete="if (#{!facesContext.validationFailed}) fireSearch()"

If validation has failed, this will ultimately result in

oncomplete="if (false) fireSearch()"

And thus the function won't be invoked.

Problem

I am using JSF2, Richfaces4 and Spring. I have a command link. On execute I save records and on complete I execute search to display records like following code. Problem is that `fireSearch()` in oncomplete executes even if there is a validation error in form. I need to execute `fireSearch()` only when the record get saved successfully. How can I the oncomplete only when validation has succeed? ``` <a4j:commandLink styleClass="button" action="#{myBean.save}" render="detail_form" execute="@form" oncomplete="fireSearch()"> <span> Save </span> </a4j:commandLink> ```
