There is the trick that works for me well, it has only one OnSubmit listener in the parent page class,Yes. Without going through a listener.
so in a way there is no listener in the actual page, only methods which we call.
I extend my pages from my OnSubmitDelegatorPage
public class OnSubmitDelegatorPage extends BasePage{private String onSubmitMethod;
public String getOnSubmitMethod(){
return onSubmitMethod;
}public void setOnSubmitMethod( String onSubmitMethod ){
this.onSubmitMethod = onSubmitMethod;
}public void onSubmit( IRequestCycle cycle ) throws Exception{
if( getOnSubmitMethod() != null ){
Method m = this.getClass().getMethod( getOnSubmitMethod(), new Class[]{IRequestCycle.class} );
if( m != null ){
m.invoke( this, new Object[]{cycle} );
}
}
setOnSubmitMethod( null );
}
}
Then in the html submit button looks like this:
<form action="" jwcid="crudForm">
<input type="submit" value="Delete" class="button" jwcid="@Submit" tag="deleteUser" selected="ognl:onSubmitMethod" />
................
This causes method deleteUser being executed by formSubmit listener after the rewind completes
And page spec says:
<page-specification class="com.kgionline.demo.tapestry.tag.pages.UserCRUDPage" >
<property-specification name="onSubmitMethod" type="java.lang.String"/> <component id="crudForm" type="Form"> <binding name="listener" expression="listeners.onSubmit"/> </component>
</page-specification>
