Examples with CaptureResultCallback org.apache.tapestry5.internal.util.CaptureResultCallback used on opensource projects

Example 1 with CaptureResultCallback

use of org.apache.tapestry5.internal.util.CaptureResultCallback 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();
}

Example 2 with CaptureResultCallback

use of org.apache.tapestry5.internal.util.CaptureResultCallback in project tapestry-5 by apache.

the class Select method onChange.

Object onChange(final EventContext context, @RequestParameter(value = "t:selectvalue", allowBlank = true) final String selectValue) throws ValidationException {
    final Object newValue = toValue(selectValue);
    CaptureResultCallback<Object> callback = new CaptureResultCallback<Object>();
    EventContext newContext = new AbstractEventContext() {

        @Override
        public int getCount() {
            return context.getCount() + 1;
        }

        @Override
        public <T> T get(Class<T> desiredType, int index) {
            if (index == 0) {
                return typeCoercer.coerce(newValue, desiredType);
            }
            return context.get(desiredType, index - 1);
        }
    };
    this.resources.triggerContextEvent(EventConstants.VALUE_CHANGED, newContext, callback);
    this.value = newValue;
    return callback.getResult();
}
