action is called twice in facelet custom tag
I have a custom tag. In there, there is an an a4j:commandLink
So I put together a facelet custom tag looks like this
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:a="http://richfaces.org/a4j"
xmlns:rich="http://richfaces.org/rich">
.....
<a:commandLink value="#{value}"
action="#{action}"
ajaxSingle="true"
reRender="#{reRender}">
<h:graphicImage value="#{icon}" />
</a:commandLink>
......
</ui:composition>
The use of the tag looks like this
.....
<my:firstTag value="Test"
action="#{bean.doSomething()}
icon="img/arrow.gif"
reRender="theForm">
</my:firstTagr>
......
The tag displayed well. If I clink on the link, the doSomething() is called OK. But a few moments later, I got and exception that looks like this
