DO NOT REPLY [Bug 52445] New: Methodexpression with arguments fails
on nested properties
https://issues.apache.org/bugzilla/show_bug.cgi?id=52445
Bug #: 52445
Summary: Methodexpression with arguments fails on nested
properties
Product: Tomcat 7
Version: 7.0.23
Platform: PC
Status: NEW
Severity: normal
Priority: P2
Component: Servlet & JSP API
AssignedTo: dev@tomcat.apache.org
ReportedBy: balusc@gmail.com
Classification: Unclassified
This is basically an improvement of issue 50449
https://issues.apache.org/bugzilla/show_bug.cgi?id=50449
Invoking a method expression with arguments fails on nested properties. I.e.
#{bean.submit('foo')} works, but #{bean.nested.submit('foo')} does not work.
com.example.Bean:
-------------------------------------------------------------------------------
package com.example;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
@ManagedBean
@RequestScoped
public class Bean {
public void submit1() {
System.out.println("Submit1 without argument");
}
public void submit1(String argument) {
System.out.println("Submit1 with argument " + argument);
}
public void submit2(String argument) {
System.out.println("Submit2 with argument " + argument);
}
public Bean getNested() {
return new Bean();
}
}
-------------------------------------------------------------------------------
test.xhtml
-------------------------------------------------------------------------------
<!DOCTYPE html>
<html lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html">

<title>Tomcat nested methodexpression test</title>
</h:head>
<h:body>
<h:form>
<h:commandButton value="bean.submit1 without argument"
action="#{bean.submit1()}" /><br/>
<h:commandButton value="bean.submit1 with argument"

<h:commandButton value="bean.submit2 with argument"

<h:commandButton value="bean.nested.submit1 without argument"
action="#{bean.nested.submit1()}" /><br/>
<h:commandButton value="bean.nested.submit1 with argument"
action="#{bean.nested.submit1('foo')}" /><br/>
<h:commandButton value="bean.nested.submit2 nested bean with argument"
action="#{bean.nested.submit2('bar')}" /><br/>
</h:form>
</h:body>
</html>
-------------------------------------------------------------------------------
Open the page and invoke the 6 buttons in sequence from top to bottom. The
result is:
-------------------------------------------------------------------------------
Submit1 without argument
Submit1 with argument foo
Submit2 with argument bar
Submit1 without argument
Submit1 without argument

Note that the 5th button invokes the wrong method (the one without arguments)
and that the 6th button throws an exception that the method cannot be found.
It's basically looking for a method without arguments.
This exception occurs regardless of if Mojarra or MyFaces is used. I tested
with Mojarra 2.1.4 and MyFaces 2.1.3 on Tomcat 7.0.23.
