Examples of javax.faces.component.UICommand

javax.faces.component.UICommand
UICommand is a base abstraction for components that implement ActionSource.


        UIComponent form = root.findComponent("testForm1");
        Assert.assertNotNull(form);
        UINamingContainer compositeComponent = (UINamingContainer) form.getChildren().get(0);
        Assert.assertNotNull(compositeComponent);
        UICommand button = (UICommand) compositeComponent.findComponent("button");
        Assert.assertNotNull(button);
        Assert.assertEquals("#{helloWorldBean.send}", button.getActionExpression().getExpressionString());
        Assert.assertEquals("#{helloWorldBean.send}", ((MethodExpression)compositeComponent.getAttributes().get("metodo")).getExpressionString());
        Assert.assertNull(button.getAttributes().get("metodo"));
        
        UICommand link = (UICommand) compositeComponent.findComponent("link");
        Assert.assertNotNull(link);
        Assert.assertEquals(1, link.getActionListeners().length);
        UIInput input = (UIInput) compositeComponent.findComponent("input");
        Assert.assertNotNull(input);
        Assert.assertEquals(1, input.getValidators().length);
        Assert.assertEquals(1, input.getValueChangeListeners().length);
