In JSP, a reference to a component defined later in the page fails
------------------------------------------------------------------
Key: MYFACES-120
URL: http://issues.apache.org/jira/browse/MYFACES-120
Project: MyFaces
Type: Bug
Versions: 1.0.8 beta
Reporter: Denis Robert
The following code (based on an example from the book JavaServer Faces in
action):
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib uri="http://java.sun.com/jsf/html"; prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core"; prefix="f" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8"/>
<title></title>
</head>
<body>
<f:view>
<p>
<h:message id="errors" for="helloInput"
style="color:red" />
</p>
<h:form id="welcomeForm">
<h:outputText id="welcomeOutput" value="Welcome to
JavaServer Faces!"
style="font-family: Arial, sans-serif;
font-size: 24; color: green" />
<p>
<h:outputLabel for="helloInput">
<h:outputText id="helloInputLabel"
value="Enter number of controls to display: " />
</h:outputLabel>
<h:inputText id="helloInput"
value="#{helloBean.numControls}" required="true">
<f:validateLongRange minimum="1"
maximum="500" />
</h:inputText>
</p>
<p>
<h:panelGrid id="controlPanel"
binding="#{helloBean.controlPanel}" columns="20" border="1" cellspacing="0" />
</p>
<h:commandButton id="redisplayCommand" type="submit"
value="Redisplay"
actionListener="#{helloBean.addControls}" />
<h:commandButton id="goodbyeCommand" type="submit"
value="Goodbye"
action="#{helloBean.goodbye}" immediate="true"
/>
</h:form>
</f:view>
</body>
</html>
causes an error:
javax.servlet.ServletException: Could not render Message. Unable to find
component 'helloInput' (calling findComponent on component 'errors')
javax.faces.webapp.FacesServlet.service(FacesServlet.java:125)
Commenting out the <h:message> tag or moving it after the <h:inputText> which
defines the helloInput component works, though.
In the RI, the code above works flawlessly.
