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

Example 1 with ComponentActionSink

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

the class AjaxFormUpdateControllerImpl method setupBeforePartialZoneRender.

public void setupBeforePartialZoneRender(MarkupWriter writer) {
    if (formComponentId == null)
        return;
    hiddenFieldPositioner = new HiddenFieldPositioner(writer, rules);
    actionSink = new ComponentActionSink(logger, clientDataEncoder);
    formSupport = createInternalFormSupport(formClientId, formComponentId, actionSink);
    environment.push(FormSupport.class, formSupport);
    environment.push(ValidationTracker.class, new ValidationTrackerImpl());
    heartbeat.begin();
}

Example 2 with ComponentActionSink

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

the class AjaxFormUpdateControllerImpl method createInternalFormSupport.

private InternalFormSupport createInternalFormSupport(String formClientId, String formComponentId, ComponentActionSink actionSink) {
    // Kind of ugly, but the only way to ensure we don't have name collisions on the
    // client side is to force a unique id into each name (as well as each id, but that's
    // JavaScriptSupport's job). It would be nice if we could agree on the uid, but
    // not essential.
    String uid = Long.toHexString(System.nanoTime());
    IdAllocator idAllocator = new IdAllocator("_" + uid);
    Component formComponent = componentSource.getComponent(formComponentId);
    CaptureResultCallback<InternalFormSupport> callback = CaptureResultCallback.create();
    // This is a bit of a back-door to access a non-public method!
    formComponent.getComponentResources().triggerEvent("internalCreateRenderTimeFormSupport", new Object[] { formClientId, actionSink, idAllocator }, callback);
    return callback.getResult();
