I'm currently trying to build a composite component, and this is how i make use of my component :
Include it with xmlns:albert="http://java.sun.com/jsf/composite/albert"
And here's the usage example
<albert:infoButton
infoId="infoSingleRecord"
params="transDateFrom transDateTo"
mappingMethod="#{tBrowseBean_ConfirmedRPB.mapSendInfoSingleRecord}" />
And this is the component which is put in resources/albert/infoButton.xhtml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.prime.com.tr/ui"
xmlns:fn="http://java.sun.com/jsp/jstl/functions"
xmlns:composite="http://java.sun.com/jsf/composite">
<composite:interface>
<composite:attribute name="infoId" required="true" />
<composite:attribute name="params" />
<composite:attribute name="mappingMethod" method-signature="java.lang.String action()" />
</composite:interface>
<composite:implementation>
<p:commandButton
process="@this #{cc.attrs.params}"
actionListener="#{cc.attrs.mappingMethod}"
update="#{cc.attrs.infoId}Panel"
oncomplete="#{cc.attrs.infoId}Dialog.show()"
image="ui-icon ui-icon-search" />
</composite:implementation>
</html>
But running it, when clicking the infoButton, this exception trace shows in my catalina.out log file :

I wonder why is this happening, because at the mywebapp.paymentplan.TBrowseBean_ConfirmedRPB, i already provide this :
public String mapSendInfoSingleRecord(ActionEvent event) {
System.out.println("mapSendInfoSingleRecord");
return null;
}
And after that, i tried putting the dummy mapSendInfoSingleRecord field, and see what happens :
private String mapSendInfoSingleRecord;
public String getMapSendInfoSingleRecord() {
return mapSendInfoSingleRecord;
}
public void setMapSendInfoSingleRecord(String mapSendInfoSingleRecord) {
this.mapSendInfoSingleRecord = mapSendInfoSingleRecord;
}
But clicking on the button now produces this exception :

I've tested against mojarra version 2.0.4-b09 and 2.1.1-b04, with the same results.
I wonder what I did wrong here ?
There are two problems:
First, the composite method-signature
which you've definied
<composite:attribute name="mappingMethod" method-signature="java.lang.String action()" />
doesn't match with the real method signature
public String mapSendInfoSingleRecord(ActionEvent event)
Second, the actionListener
methods should return void
not String
.
I assume that you just want a action
method, you should then change the real method signature to get rid of the ActionEvent
argument:
public String mapSendInfoSingleRecord()
As to actionListener
vs action
, you may find this question/answer useful: Differences between action and actionListener.
