@jonas ignore that. i was just refactoring the code for the email. the error is runtime not compile time. I think it is a conversion problem please help The field parentid is integer but the dropdown is expecting object the form <code> IModel zaModel=new CompoundPropertyModel(selected); departmentform.setModel(zaModel); RequiredTextField departmentname=new RequiredTextField("departmentname"); departmentname.setOutputMarkupId(true); departmentform.add(departmentname);
DepartmentDropDownChoice title=new DepartmentDropDownChoice("parentid",zaModel); departmentform.add(title); departmentform.add(new AjaxFallbackLink("canceldepartmentformbutton"){ @Override public void onClick(AjaxRequestTarget target) { closeModalWindow(target); } }); feedback = new FeedbackPanel("feedback"); feedback.setOutputMarkupId(true); int[] filteredErrorLevels = new int[]{FeedbackMessage.ERROR}; feedback.setFilter(new ErrorLevelsFeedbackMessageFilter(filteredErrorLevels)); departmentform.add(feedback); FeedbackLabel departmentFeedbackLabel = new FeedbackLabel("departmentfeedback", departmentname,new Model("Department is required")); departmentFeedbackLabel.setOutputMarkupId(true); departmentname.add(new ComponentVisualErrorBehavior("onblur", departmentFeedbackLabel)); departmentform.add(departmentFeedbackLabel); departmentform.add(new AjaxFallbackButton("savedepartmentbutton", departmentform) { @Override protected void onSubmit(AjaxRequestTarget target, Form<?> form) { PersonnelrecordsDepartment pr=(PersonnelrecordsDepartment)form.getDefaultModel().getObject(); try { if(isNew){ dao.addPersonnelrecordsDepartment(pr); } else{ dao.savePersonnelrecordsDepartment(pr); } } catch (GenericBusinessException ex) { Logger.getLogger(DepartmentPanel.class.getName()).log(Level.SEVERE, null, ex); } //target.addComponent(form); setFormReponse(target); } @Override protected void onError(AjaxRequestTarget target, Form<?> form) { // repaint the feedback panel so errors are shown target.addComponent(feedback); } }); add(departmentform); } private void setFormReponse(AjaxRequestTarget target){ info("Save Operation was Successful"); target.addComponent(feedback); } FeedbackPanel feedback; } </code> On 1/20/10, Jonas <barney...@gmail.com> wrote: > not sure if that's the problem, but shouldn't > > setChoices(titles); > > be > > setChoices(departments); > > > > > On Wed, Jan 20, 2010 at 4:14 PM, chinedu efoagui <chinedub...@gmail.com> > wrote: >> Hello , I have a class PersonnelrecordsDepartment >> with the following fields with corresponding getters and setters >> private java.lang.Integer id; >> private java.lang.String departmentname; >> private java.lang.Integer parentid; >> >> I left out the getters and setters .
