Hi! In UIComponentTagUtils the "Void"-check for the return-type of the listener cant be evaluated e.g. within an dataTable - or any other component using a var= attribute. This is due to the fact that the var= attribute hasnt processed so far and thus the getType() cant find the method (base is null)
javax.faces.el.EvaluationException: Cannot get type for expression #{newPrm.changeFieldEnabledListener} at org.apache.myfaces.el.MethodBindingImpl.getType(MethodBindingImpl.java:101) at org.apache.myfaces.taglib.UIComponentTagUtils.setValueChangedListenerProperty(UIComponentTagUtils.java:318) at org.apache.myfaces.taglib.UIComponentTagBase.setValueChangedListenerProperty(UIComponentTagBase.java:187) at org.apache.myfaces.taglib.html.HtmlInputTagBase.setProperties(HtmlInputTagBase.java:60) at org.apache.myfaces.taglib.html.HtmlSelectMenuTagBase.setProperties(HtmlSelectMenuTagBase.java:87) at javax.faces.webapp.UIComponentTag.findComponent(UIComponentTag.java:574) at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:312) at What to do now? I think the first thing to do is to remove these checks, later we can find a better approach. I guess the check can only be done when it will be fired (if possible then) as the var= will only be available during encoding or decoding the component. --- Mario
