Martin Koci commented on MYFACES-2541:
--------------------------------------
Problem with variableMapper:
1) template client:
<h:body >
<ui:decorate template="template.xhtml">
<ui:param name="bean" value="#{beanA}" />
</ui:decorate>
</h:body>
2) Template:
<f:subview xmlns:f="http://java.sun.com/jsf/core";
xmlns:h="http://java.sun.com/jsf/html";>
<h:form >
<h:commandButton value="Click" actionListener="#{bean.processAction}" />
</h:form>
</f:subview>
a) if bean.processAction is method with actionEvent there is no problem and
method is called
b) id bean.processAction is method without actionEvent param ->
javax.el.PropertyNotFoundException: Target Unreachable, identifier 'bean'
resolved to null
at org.apache.el.parser.AstValue.getTarget(AstValue.java:67)
at org.apache.el.parser.AstValue.invoke
Explanation: TagAttribute.getMethodExpression creates a MethodExpression with
variableMapper (because it is aware of facelets context, but
ExpressionFactory.createMethodExpression() used in
MethodExpressionActionListener cannot reach to facelets mapping. It can be easy
seen while debugging: first MethodExpression has a orig.varMapper attribute
with "bean = beanA", but second MethodExpression created in
MethodExpressionActionListener has this attribute null.
