a4j:jsFunction actionListener not listening

The listener is:

public void renderer(ActionEvent event) {
    System.out.println("here=========================");
    System.out.println();
    System.out.println();
    System.out.println();
    System.out.printl开发者_如何学Pythonn();
    System.out.println();
    System.out.println();
    System.out.println();
    System.out.println();
    System.out.println();
    System.out.println();
    System.out.println();
    System.out.println();
    setOptimizeActionDTOs(null);
}

and setOptimizeActionDTOs

public void setOptimizeActionDTOs(List<OptimizeActionDTO> optimizeActionDTOs) {
    this.optimizeActionDTOs = optimizeActionDTOs;
}

And the a4j:jsFunction is:

<a4j:form>          
    <a4j:jsFunction name="renderOptimizeActionList" actionListener="#{rtopHandler.renderer}" oncomplete="renderOptimizeActionList1();"/>
    <a4j:jsFunction name="renderOptimizeActionList1" reRender="profilealertpanel1"></a4j:jsFunction>
    <script language="JavaScript">
        renderOptimizeActionList();
    </script>
</a4j:form>

But I can't see any output of the System.out. Why? Any information will be very helpful to me.

Thank you.

Try putting your <script> tags outside the <form> tags. Further, you can check whether the <a4j:jsFunction> is called by putting an "alert()" on onbegin event of the <a4j:jsFunction/>
