Examples with FormSupportAdapter org.apache.tapestry5.corelib.internal.FormSupportAdapter used on opensource projects

Example 1 with FormSupportAdapter

use of org.apache.tapestry5.corelib.internal.FormSupportAdapter in project tapestry-5 by apache.

the class FormFragment method beginRender.

/**
 * Renders a <div> tag and provides an override of the {@link org.apache.tapestry5.services.FormSupport}
 * environmental.
 */
void beginRender(MarkupWriter writer) {
    FormSupport formSupport = environment.peekRequired(FormSupport.class);
    String clientId = getClientId();
    hiddenFieldPositioner = new HiddenFieldPositioner(writer, rules);
    Element element = writer.element(this.element, "id", clientId, "data-component-type", "core/FormFragment");
    if (alwaysSubmit) {
        element.attribute("data-always-submit", "true");
    }
    resources.renderInformalParameters(writer);

            javascriptSupport.require("t5/core/form-fragment").invoke("hide").with(clientId);
        }
    }
    componentActions = new ComponentActionSink(logger, clientDataEncoder);
    // Here's the magic of environmentals ... we can create a wrapper around
    // the normal FormSupport environmental that intercepts some of the behavior.
    // Here we're setting aside all the actions inside the FormFragment so that we
    // can control whether those actions occur when the form is submitted.
    FormSupport override = new FormSupportAdapter(formSupport) {

        @Override
        public <T> void store(T component, ComponentAction<T> action) {
            componentActions.store(component, action);
        }

        @Override
        public <T> void storeCancel(T component, ComponentAction<T> action) {
            componentActions.storeCancel(component, action);
        }

        @Override
        public <T> void storeAndExecute(T component, ComponentAction<T> action) {
            componentActions.store(component, action);
            action.execute(component);
        }
    };
    // Tada! Now all the enclosed components will use our override of FormSupport,
    // until we pop it off.
    environment.push(FormSupport.class, override);
}

Example 2 with FormSupportAdapter

use of org.apache.tapestry5.corelib.internal.FormSupportAdapter in project tapestry-5 by apache.

the class Zone method beginRender.
