richfaces - JSF Composite Component with conditional popup panel -

i'm trying render composite component shows popup panel based on outcome of backing bean method. far no success. appreciate help.

• glassfish 4.1
• mojarra 2.2
• richfaces 4.5.4

composite component (conditionalactionlink.xhtml):

<ui:component xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:composite="http://java.sun.com/jsf/composite">  <composite:interface>     <composite:attribute name="value"/>     <composite:attribute name="style"/>     <composite:attribute name="disabled"/>     <composite:attribute name="render"/>     <composite:attribute name="message" />     <composite:attribute name="renderedbtn" type="java.lang.boolean"/>     <composite:attribute name="condition" required="true" method-signature="java.lang.boolean action()"/>     <composite:attribute name="execaction" required="true" method-signature="void action()"/> </composite:interface> <composite:implementation>     <ui:debug hotkey="x" />     <h:form>         <a4j:commandlink id="actnlnx" value="#{cc.attrs.value}" oncomplete="#{managepurchases.billhaspaymentsapplied ? showmessage() : submittoserver() }" style="#{cc.attrs.style}" disabled="#{cc.attrs.disabled}"/>         <a4j:jsfunction name="showmessage" onbegin="#{rich:component('noticedialog')}.show()" execute="@form"/>         <a4j:jsfunction name="submittoserver" action="#{cc.attrs.execaction}" render="#{cc.attrs.render}" execute="@form"/>                       <rich:popuppanel id="noticedialog" modal="true" autosized="true" resizeable="false" style="font-size: large;">             <f:facet name="header" style="font-size: large;">                 <h:outputtext value="notice" />             </f:facet>             <f:facet name="controls">                 <h:outputlink value="#" onclick="#{rich:component('noticedialog')}.hide(); return false;">                     x                 </h:outputlink>             </f:facet>             <h:outputtext value="#{cc.attrs.message}"/>             <br/><br/>             <h:commandbutton value="ok" onclick="#{rich:component('noticedialog')}.hide(); return false;" style="font-size: large;"/>         </rich:popuppanel>       </h:form> </composite:implementation> 

invoking page:

<cc:conditionalactionlink value="delete" style="font-size: large;text-decoration:none" message="this bill has payments applied. please delete payments first." condition="#{managepurchases.billhaspaymentsapplied}" execaction="#{managepurchases.deletebill}"/> 

btw, need use condition value in composite component, challenged how avoid nested el expression: oncomplete="#{cc.attr.condition ? showmessage() : submittoserver() }"

backing bean:

public boolean getbillhaspaymentsapplied(){     applogger.entry();     //if(bill.getpayments().size() > 0)         return applogger.exit(true);     //else         //return applogger.exit(false); }  public void deletebill(){     applogger.entry();      applogger.debug("delete bill here.");     //billdaobean.deletebill(bill);      applogger.exit();  } 

i've tried many tweaks, search online. particular version, error message

javax.el.elexception: function 'showmessage' not found

i seeking way achieve behavior.

thanks in advance!

the oncomplete attribute of <a4j:commandlink> component must evaluate string. here, el tries invoke either showmessage() or submittoserver() java method depending on boolean value, not found.

what want string js function name, put function names between single quotes make them string:

oncomplete="#{managepurchases.billhaspaymentsapplied ? 'showmessage()' : 'submittoserver()'}" 

i dont have richfaces-ready playground (by way, never used richfaces either), can't test, should trick !
