Custom Tag: Cannot find setter method for attribute

Question

This has been working fine in appserver6.5.
In the jsp:
=======
<display:table configFileDir="theDirectory"...>
=======
The tld entry:
<tag>
<name>table</name>
<tagclass>org.apache.taglibs.display.TableTag</tagclass>
<teiclass>org.apache.taglibs.display.TableTagExtraInfo</teiclass>
<bodycontent>JSP</bodycontent>
<attribute>
<name>configFileDir</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
=============
In TableTag.java:
=============
private String configFileDir = null;
public void setConfigFileDir( String v )
     v = v.trim();
this.configFileDir = v;
============
Help, I'm going nuts.

Then you also need to create a UI element that extends HtmlPanelGrid
that has a tModelKey member and getters/setters. That object will hold
the information so that you can use it in your bean.Whoops... ignore that! Sorry. Attributes are simply stored in the component map component.getAttributes().
Add to your Tag class:
public void setProperties(UIComponent component) {
    super.setProperties(component);
    Tags.setString(component, "tModelKey", tModelKey);
public void release() {
    // see above
}Where Tags.java is:public class Tags {
    public static void setString(UIComponent component, String attributeName, String attributeValue) {
        if (attributeValue != null) {
            if (UIComponentTag.isValueReference(attributeValue)) {
                setValueBinding(component, attributeName, attributeValue);
            } else {
                component.getAttributes().put(attributeName, attributeValue);
    public static void setValueBinding(UIComponent component, String attributeName, String attributeValue) {
        FacesContext context = FacesContext.getCurrentInstance();
        Application app = context.getApplication();
        ValueBinding vb = app.createValueBinding(attributeValue);
        component.setValueBinding(attributeName, vb);
}
