Key: MYFACES-3112 URL: https://issues.apache.org/jira/browse/MYFACES-3112 Project: MyFaces Core Issue Type: Bug Components: JSR-314 Affects Versions: 2.0.5 Environment: Apache Maven 2.2.1 (r801777; 2009-08-06 21:16:01+0200) Java version: 1.6.0_24 Java home: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home Default locale: en_US, platform encoding: MacRoman OS name: "mac os x" version: "10.6.7" arch: "x86_64" Family: "mac" MyFaces 2.0.5 OWB: 1.1.0 CoDI 0.9.4 Reporter: Matthias Weßendorf In my "newEmployee.xhtml" I am using a custom facelets component, like: <kickstart:inputPassword id="password" value="#{createEmployee.employee.password}" valueChangeListener="#{createEmployee.checkPassword}" /> The inputPassword.xhtml looks like: <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:composite="http://java.sun.com/jsf/composite"> <head/> <body> <composite:interface> <composite:attribute name="id" required="true" /> <composite:attribute name="value" required="true" /> <composite:attribute name="valueChangeListener" required="true" method-signature="void f(javax.faces.event.ValueChangeEvent)" targets="inputField" /> <composite:editableValueHolder name="inputField" /> </composite:interface> <composite:implementation> <div id="#{cc.attrs.id}"> <h:inputSecret id="inputField" required="true" value="#{cc.attrs.value}" valueChangeListener="#{cc.attrs.valueChangeListener}"> <f:ajax event="valueChange" execute="@this" render="passwordHint pageForm:globalMessages" /> </h:inputSecret> <h:outputText id="passwordHint" /> </div> </composite:implementation> </body> </html> When I type in a value, and move the focus away (to trigger the valueChange event), I am getting the below stack-trace in the console: SEVERE: java.lang.IllegalArgumentException: Cannot convert /newEmployee.xhtml at line 39 and column 160 valueChangeListener="#{createEmployee.checkPassword}":
