Greg,
Does the truncateOutput tag work with JSF EL?
The following snippet causes a NullPointerException in the
TruncateConverterTag at line 62, which is marked below because
the Object o is always null.
<t:columns id="columns"
value="#{MyControllerBean.columnHeaders}"
var="columnHeader">
<h:outputText value="#{DynaAnnoControllerBean.cellValue}">
<rm:truncateOutput truncateAt="#{columnHeader.truncateAtPosition}"
continuationMark="..."/>
</h:outputText>
private static void setConverterTruncateAt(FacesContext facesContext,
TruncateConverter converter, String value) {
if (value == null) {
converter.setTruncateAt(0);
} else if (UIComponentTag.isValueReference(value)) {
ValueBinding vb =
facesContext.getApplication().createValueBinding(value);
Object o = vb.getValue(facesContext);
if (o instanceof Number) {
converter.setTruncateAt(((Number) o).intValue());
} else {
converter.setTruncateAt(Integer.parseInt(o.toString()));
//line 62
}

I'm also use MyFaces 1.1.1 with Tomcat 5.0.25.
I don't know what's causing the errors your getting.
The only changes I made to the code I posted was:
- changed the package to xxx
- removed the uri info from the TLD
<uri>http://xxx.xxx/xxx</uri>
- I didn't show the taglib tag
<%@ taglib prefix="xxx" uri="http://xxx.xxx/xxx"%>
- I didn't show the TLD doctype (see below)
Ensure your xxx.tld is in WEB-INF and starts:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library
1.2//EN" "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd";>
<taglib>...
