Binding problem...

[Roberto Marra]

Hi guys, still here with some problem of binding. Let me explain the situation. First of all a snipped of how the file are made:   -- Binding file -- ... <fb:value id="indirizzo1" path="indirizzo"/> <fb:value id="cap" path="cap"/> <fb:_javascript_ id="nazione" path="."> <fb:load-form/> <fb:save-form>     var formValue = widget.getValue();     var appValue = doCountryConversion(formValue);     jxpathPointer.setValue(appValue); </fb:save-form> </fb:_javascript_> ... -- File definition -- ... <!-- Nazione --> <fd:field id="nazione">   <fd:label>Nazione:</fd:label>   <fd:datatype base="string"/>   <fd:selection-list src="cocoon:/nazioni.list"/> </fd:field> ...   -- Java Bean --   public class ContactBean {       private Country nazione;       public Country getNazione(){     return this.nazione;   }       public void setNazione(Country _nazione){       this.nazione = _nazione;   }   }   The problem is when the binding is doing this "jxpathPointer.setValue(appValue);" I got this error:   An Error Occurred uncaught _javascript_ exception: at contatti (file:/D:/Programmi/Apache Group/cocoon-2.1.5.1/build/webapp/mf/flow/contatti.js, Line 41) at (resource://org/apache/cocoon/forms/flow/_javascript_/Form.js, Line 171): org.apache.avalon.framework.CascadingRuntimeException: Error invoking _javascript_ event handler org.apache.avalon.framework.CascadingRuntimeException: uncaught _javascript_ exception: at contatti (file:/D:/Programmi/Apache Group/cocoon-2.1.5.1/build/webapp/mf/flow/contatti.js, Line 41) at (resource://org/apache/cocoon/forms/flow/_javascript_/Form.js, Line 171): org.apache.avalon.framework.CascadingRuntimeException: Error invoking _javascript_ event handler cause: org.mozilla._javascript_._javascript_Exception: at top-level script (file:/D:/Programmi/Apache Group/cocoon-2.1.5.1/build/webapp/mf/binding/contatti/contatti.xml, Line 14): java.lang.NullPointerException The contatti.xml, Line 14 correspond to "jxpathPointer.setValue(appValue);" but appValue is not null there is a value!!   Any suggestion is welcome.   Thanx in advance Roberto
