I typically set the name parameter, and validate=false when going through my populate actions. - - By using HttpServletRequest.setAttribute("myStringList", dataObjectArray); name-attribute, as far as I know, defines the form where we want to read the data, it's not necessary in actions where you just throw some stuff to request. > > <action path="/readMyForm" > type="test.editFormAction" > scope="request" > name="forms.myForm" > <forward name="success" path="myResultPage.jsp" /> > </action> > > - - - - Prepopulated form: > <logic:iterate id="value" name="myStringList"> > <html:text property="values" value="${value}" indexed="true" /> > </logic:iterate> > > - - - - Action: > DynaActionForm dynaForm = (DynaActionForm) myForm; > List myList = (List) dynaForm.get("values"); > > The form shows up fine, but somehow the List I retrieve > doesn't contain > any elements.
