Gilliard Cordeiro commented on JBSEAM-1913:
-------------------------------------------

for instance...

in web.xml
<context-param>
	<param-name>facelets.LIBRARIES</param-name>
	<param-value>/WEB-INF/mylib.taglib.xml</param-value>
</context-param>

mylib.taglib.xml
<?xml version="1.0"?>
<!DOCTYPE facelet-taglib PUBLIC
  "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
  "http://java.sun.com/dtd/facelet-taglib_1_0.dtd">

<facelet-taglib>
	<namespace>http://mycompany/components</namespace>

	<tag>
		<tag-name>myComp</tag-name>
		<source>../components/myComponent.xhtml</source>
	</tag>

in myComponent.xhtml
<ui:composition...>

<!-- My other components -->
<h:commandButtom action="#{myAction}"/>
</ui:composition>

in my test.xhtml page...

<html xmlns="http://www.w3.org/1999/xhtml"
	xmlns:my="http://mycompany/components"
...
>

<!-- other page elements -->

<h:inputText value="#{managedBean.testValue}"/>
<my:myComp myAction="#{managedBean.action(managedBean.testValue)}"/>
<h:commandButton action="#{managedBean.action(managedBean.testValue)}"/>
</html>

in managedBean

public void action(String testParameter)
{
    System.out.println(testParameter);
}

--------------------------

When executing managedBean.action invoked by commandButton in myComp, the parameter testParameter is null. But, when executing managedBean.action invoked by commandButton in test.xhtml, the parameter testParameter is correct.
