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
