I've fought this alot before. I'm not sure what causes it exactly. I'm
using eclipse 3.2, with the webtools platform and sometimes I think it
is just that eclipse is not properly updating the deployment to
tomcat.
I'm not sure what you're using for development but after some googling
I found this:
http://forum.java.sun.com/thread.jspa?threadID=694130&messageID=4054739
which suggests a couple things.
Good luck, and if you figure it out let me know I'm trying to collect
a whole bunch of "gotchas"

this is how that bean is configure in faces-config..:
<managed-bean>
<managed-bean-name>loginBean</managed-bean-name>
<managed-bean-class>no.havleik.dt.jsf.LoginBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
And this is the relevant part of jsp that uses that bean..:
<h:panelGrid columns="2" border="0" cellpadding="5" cellspacing="3"
headerClass="login-header">
<f:facet name="header">
<h:outputText value="#{bundle.appLoginTitle}"/>
</f:facet>
<h:panelGroup/>
<h:messages globalOnly="true" styleClass="errors"/> <!>
<h:outputLabel value="Brukernavn:" for="username"></h:outputLabel>
<h:panelGroup>
<h:inputText id="username" size="30" maxlength="30" required="true"
value="#{loginBean.j_username}">
<f:validateLength minimum="2" maximum="30"/>
</h:inputText>
<h:message for="username" styleClass="errors"/>
</h:panelGroup>
<h:outputLabel value="Passord:" for="password"></h:outputLabel>
<h:panelGroup>
<h:inputSecret id="password" size="30" maxlength="40" required="true"
value="#{loginBean.j_password}">
<f:validateLength minimum="2" maximum="40"/>
</h:inputSecret>
<h:message for="password" styleClass="errors"/>
</h:panelGroup>
<h:panelGroup/>
<h:commandButton action="#{loginBean.login}" title="Logg inn" value="Logg
inn"/>
</h:panelGrid>
</td>
And if you remove the two myfaces*.jar files and replace them with jsf*.jar it
works...
Can anyone shed any light?
btw, I am also using tiles but the tiles files is not used until after logon...
not sure if this info is of any use but...
Regards,
BTJ
