Re: ClassCastException with f:verbatim

[Grant Smith]

Is there a JIRA issue for this ? If not, please add one :)

Thanks,
Grant

Ok, looks like my problem is related to this one:

http://www.mail-archive.com/users@myfaces.apache.org/msg03517.html

(and if I remove my verbatim tags I get the duplicate ID problem instead)

I presume there has been no progress on this issue as yet?

Hi,

I'm getting an odd intermittent problem with the f:verbatim tag:

005-05-06 13:04:27,511 ERROR [org.jboss.web.localhost.Engine] ----- Root Cause -----
java.lang.ClassCastException
at org.apache.myfaces.taglib.core.VerbatimTag.doAfterBody(VerbatimTag.java:76)

at org.apache.jsp.project.projectPage_jsp._jspx_meth_f_verbatim_1(projectPage_jsp.java:741)

at org.apache.jsp.project.projectPage_jsp._jspService(projectPage_jsp.java:103)

at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94)

In my case the VerbatimTag contains  

public int doAfterBody() throws JspException {
       BodyContent bodyContent = getBodyContent();
       if (bodyContent != null) {
           UIOutput component = (UIOutput)getComponentInstance();
           component.setValue(bodyContent.getString());
       }
       return super.doAfterBody();
}

The offending line is:

UIOutput component = (UIOutput)getComponentInstance();

where the getComponentInstance() is returning an HTMLCommandLink (and it is expecting UIOutput)

A snippet of the offending JSP is:

<f:view>
...
<h:panelGrid columns="1" styleClass="rightAlignedTable" style="width:100%">
<h:panelGroup>
<h:commandLink action="#{ProjectController.editProject}" styleClass="button">
<h:commandButton value="Edit Project" styleClass="buttonMedium"/>
<f:param name="projectUuid" value="#{ProjectController.project.uuid}" />
</h:commandLink>
<f:verbatim>&nbsp;</f:verbatim>
<h:commandLink action="#{ProjectController.manageProject}" styleClass="button">
<h:commandButton value="Manage Project" styleClass="buttonMedium" disabled="true"/>
</h:commandLink>
<f:verbatim>&nbsp;</f:verbatim>
<h:commandLink action="#{ProjectController.closeProject}" styleClass="button">
<h:commandButton value="Close Project" styleClass="buttonMedium"/>
</h:commandLink>
</h:panelGroup>
</h:panelGrid>
</f:view>

(I know it is 'odd' to have commandButtons within commandLinks)

Any ideas? Is there a better way to render non-breaking spaces?

Thanks,

Sean
