How to stop event specified in a4j:support on certain conditions?

I have a4j:support inside a certain component. What i wanted to do is to disable the sending of ajax request on the component on certain conditions. How can i disable a4j:support/a4j:ajax not to fire the ajax request on that component. Let say for example a certain click on that component.

Thanks :)

Solution

  • Return false on the submit event of a4j:support:

    <a4j:support id="myField"
             event="onblur" 
             onsubmit="if(valid()==false){return false;}" 
             oncomplete="complete();" 
             actionListener="#{myBacking.myAction}" 
             reRender="myOtherFields" />

    valid() returns true or false, if it returns true, you do nothing (don't return true).
