How to display form validation constraints message on GWT Material inputs using Editor and Validation Framework from Presenter's class? -
i use:
after constraints validation display error messages. supported gwt material inputs, materialtextbox using method: materialtextbox.seterror("please provide name");
the problem can executed view class:
public class loginview extends viewwithuihandlers<loginuihandlers> implements loginpresenter.myview { interface binder extends uibinder<widget, loginview> {} /** driver link proxy bean view. */ public interface editordriver extends simplebeaneditordriver<loginmodel, loginview> { } @uifield materialtextbox email; @uifield materialtextbox password; @uifield materialbutton loginbutton; @uifield materialcheckbox keepmeloggedincheckbox; @inject loginview(binder uibinder) { initwidget(uibinder.createandbindui(this)); addclickhandlertologinbutton(); } //@uihandler("loginbutton") private void onloginbuttonclick(clickevent e){ getuihandlers().onloginbuttonclick(); } private void addclickhandlertologinbutton() { loginbutton.addclickhandler(new clickhandler() { @override public void onclick(clickevent event) { onloginbuttonclick(event); } }); } @override public simplebeaneditordriver<loginmodel, ?> createeditordriver() { editordriver driver = gwt.create(editordriver.class); driver.initialize(this); return driver; } public void test() {} } but editor/validation action in presenter, , not have there view connection use:
public class loginpresenter extends presenter<loginpresenter.myview, loginpresenter.myproxy> implements loginuihandlers { public interface myview extends beaneditview<loginmodel>, hasuihandlers<loginuihandlers> {} public static final type<revealcontenthandler<?>> slot_login = new type<revealcontenthandler<?>>(); @proxystandard @nametoken(nametokens.login) public interface myproxy extends proxyplace<loginpresenter> {} // editor private simplebeaneditordriver<loginmodel, ?> editordriver; private static final loginservice service = gwt.create(loginservice.class); private loginmodel model = new loginmodel("",""); @override public void onloginbuttonclick() { if (editordriver.isdirty()) { model = editordriver.flush(); validatemodel(); if (editordriver.haserrors()) { materialtoast.firetoast("errors occur"); stringbuilder errorbuilder = new stringbuilder(); (editorerror error : editordriver.geterrors()) { errorbuilder.append(error.getmessage() + "\n"); } materialtoast.firetoast(errorbuilder.tostring()); } else { service.login( model, new methodcallback<integer>() { @override public void onsuccess(method method, integer response) { materialtoast.firetoast("succefully set info. status code: " + response); } @override public void onfailure(method method, throwable exception) { materialtoast.firetoast("error setting"); } }); } } else { materialtoast.firetoast("data has not changed"); } } private void validatemodel() { validator validator = validation.builddefaultvalidatorfactory().getvalidator(); set<constraintviolation<loginmodel>> violations = validator.validate(model); if (violations.size() > 0) { editordriver.setconstraintviolations(new arraylist<constraintviolation<?>>(violations)); } } @inject loginpresenter(eventbus eventbus,myview view, myproxy proxy) { super(eventbus, view, proxy, revealtype.root); getview().setuihandlers(this); editordriver = getview().createeditordriver(); editordriver.edit(model); } } i think should add interface declare methods access inputs in view. , implementation of that. don't know how. please me.
i've make working. not quite sure did happened start work. share working code:
