I'm trying to use the wicketstuff.org JSR-303 validation project to use Hibernate Validator in my newish Wicket project.
I have a FormComponentPanel with a model object set up for JSR-303 validation, but we are using vanilla Wicket Validators for it. To test the FormComponentPanel, I wrote a test panel which includes a form, which includes the FormComponentPanel. When I add the WicketStuff PropertyValidation behavior to the test panel (which I then use with a WicketTester based JUnit test class): //CategoryTestPanel Form<Marking> form = new Form<Marking>("form", new CompoundPropertyModel<Marking>(marking)); form.add(new PropertyValidation()); add(form); form.add(new CategoryPanel("category")); form.add(new Button("submit")); and //CategoryPanelTest @Before public void initTester() { tester = new WicketTester(); tester.startPanel(CategoryTestPanel.class); formTester = tester.newFormTester("form"); } I get this exception: org.apache.wicket.WicketRuntimeException: Cannot modify component hierarchy after render phase has started (page version cant change then anymore) at org.apache.wicket.Component.checkHierarchyChange(Component.java:3521) at org.apache.wicket.Component.addStateChange(Component.java:3450) at org.apache.wicket.Behaviors.add(Behaviors.java:62) at org.apache.wicket.Component.add(Component.java:4431) at org.apache.wicket.markup.html.form.FormComponent.add(FormComponent.java:490) at org.wicketstuff.jsr303.PropertyValidation.addValidator(PropertyValidation.java:76) at org.wicketstuff.jsr303.PropertyValidation.access$000(PropertyValidation.java:17) at org.wicketstuff.jsr303.PropertyValidation$JSR303ValidatorFormComponentVisitor.component(PropertyValidation.java:32) at org.wicketstuff.jsr303.PropertyValidation$JSR303ValidatorFormComponentVisitor.component(PropertyValidation.java:22) ***redacted*** Note that vlaidators are already being added to the FormComponentPanel object, and they work fine. Where should I add the validation behavior? Is there a better JSR303 library to use (inside a public Maven repository)?
