my advice is : go to t5 source copy paste submit component into your own upgrade it a bit and youoll get all you need.
The submit component calls the selected event on parent component, you must create a component to get events here's source code for submit component that can cancel a from (it is a copy/paste from t5, plus some aditions) and also call onCancel event // Copyright 2007, 2008 The Apache Software Foundation // // Licensed under the Apache License, Version 2.0 (the "License"); // you may not use this file except in compliance with the License. // You may obtain a copy of the License at // // http://www.apache.org/licenses/LICENSE-2.0 // // Unless required by applicable law or agreed to in writing, software // distributed under the License is distributed on an "AS IS" BASIS, // WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. // See the License for the specific language governing permissions and // limitations under the License. package tapestryutil.components; import org.apache.tapestry.ComponentEventCallback; import org.apache.tapestry.ComponentResources; import org.apache.tapestry.MarkupWriter; import org.apache.tapestry.TapestryConstants; import org.apache.tapestry.annotations.Environmental; import org.apache.tapestry.annotations.Mixin; import org.apache.tapestry.annotations.Parameter; import org.apache.tapestry.corelib.base.AbstractField; import org.apache.tapestry.corelib.mixins.RenderDisabled; import org.apache.tapestry.internal.services.ComponentResultProcessorWrapper; import org.apache.tapestry.ioc.annotations.Inject; import org.apache.tapestry.services.ComponentEventResultProcessor; import org.apache.tapestry.services.FormSupport; import org.apache.tapestry.services.Heartbeat; import org.apache.tapestry.services.Request; import org.apache.tapestry.services.Traditional; /** * Corresponds to <input type="submit">, a client-side element that can force the enclosing form to submit.
