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.");
}
}
-----------------------------
View.page
---------------------------
<?xml version="1.0" encoding="UTF-8"?>

"http://jakarta.apache.org/tapestry/dtd/Tapestry_4_0.dtd";>
<page-specification class="View">

--------------------------
View.html:
---------------------------
Hello!
<form jwcid="@Form" listener="ognl:listeners.onSubmit">
<input type="submit" value="Submit" />
</form>
-----------------------------
Exception:
