I'm getting the following error once I try to invoke the component on jboss-eap-5.0 application server but it works fine on Jboss 4.2.3 GA server.
Component j_id1:j_id10 not instance of org.ajax4jsf.component.UIAjaxCommandLink
Any help on this will be appreciated.
Since it appears you are using EAP you are likely entitled to support through the JBoss customer support portal. They provide excellent support, and any issues come through the product team quickly.
