Problem with Tapestry Form in portlet
Hi!
I'm developing portlet application with T4.
There is a strange exception when I'm trying to add Form element on html
template: "Parameter servletPath must not be null." I'm using uPortal as a
portlet container.
Mayby there are special components for portlets?
View.java
------------------------
import org.apache.tapestry.html.BasePage;
public class View extends BasePage {
public void onSubmit() {
System.out.println("Listener 'onSubmit' called.");
}
}

Thank for your attention. The problem is I don't have any hivemodule.xml.
Is it mandatory?

I believe you have cut-n-pasted the friendly URL configuration into
your hivemodule.xml. Friendly URLs don't make sense in the portlet
world (portlet URLs are always very ugly) and the friendly URL logic
relies on the Servlet API. Remove that from your hivemodule.xml and
you should be good.
