Integration of WO in JSP page

I've been testing the J2EE features of WO. Running a WO app as  
servlet is fairly easy. Integrating WO components and actions in JSP  
pages on the other hand seems to be a bit more difficult. Has anyone  
of you any experiences an recommendations to share?

E.g.:
- How to use component actions? All I can come up with are pretty bad  
hacks including filter servlets and so on...

- How to pass more than one form value to a <wo:directAction /> tag.  
There seems to be a bug. I've got the following tag in my JSP page

   	<wo:directAction actionName="test" className="DirectAction">
   		<wo:formValue key="testCount" value='<%= request.getParameter  
("testcount") %>' />
   		<wo:formValue key="detailPath" value="features.html" />
   	</wo:directAction>

"detailPath" was always empty (null), so I logged out the list of  
form value keys the direct action received:

INFO   WOServletTest NSLog.java(appendln:1546) 25.07.2006 12:21:28   
("amp;detailPath", "testCount")

The form values seem to be added and passed on to wo like so:  
testCount=3&detailPath=features.html. But then the string is not  
split up correctly anymore. This of course would be a small thing to  
fix... if it was open source :-(
Maybe I should just write my own custom tag library?
