Thanks! Right on the money.

Ooops, should have looked down farther in your email for the answer :)

Remove this line from your html:

<input type="hidden" name="action" value="portlets.SharedStateAction"/>

This is what is causing turbine to prematurely fire your action before  
the portlet has had a chance to render.

Are you setting the action in the form action or in the form field?   
If
so, you will not have access to the portlet because turbine excutes
actions defined in this manner prior to the portlet rendering.

Try adding and "action" parameter to the portlets registry entry, if  
you
have not already done so, and do not specify the action within your  
form.
This way the portlet's getContent() method will invoke the action  
instead
of turbine.  The portlet's getContent() will also "stuff" the context
things like the Portlet, PortletInstance, etc.

Subject: Empty Context in do* methods
I'm just getting started with Jetspeed so hopefully I haven't missed
something obvious.
I am developing a Message-of-the-Day style portlet that stores its
message as a parameter in the xreg. Everything seems to be working
except when it goes to run my do* method, the Context is always empty
so I can't seem to find a Portlet reference anywhere. I found a
workaround my going to the Registry and hardcoding the name of the
Portlet but this seems hack-ish.
Do I need to configure something to get the portlet stuck into the
context? I've run the debugger and in the call stack above me, the
context is always empty. It is working on the build* methods, just  
not
the do* method. I've snipped the relevant fragments below.

=============================
the .xreg:
     <portlet-entry name="SharedStatePortlet" hidden="false"  
type="ref"
         parent="GenericMVCPortlet" application="false">

<classname>org.apache.jetspeed.portal.portlets.GenericMVCPortlet</
classname>
         <parameter name="template" value="sharedState.jsp"
hidden="true"
             cachedOnName="true" cachedOnValue="true"/>
         <parameter name="action" value="portlets.SharedStateAction"
             hidden="true" cachedOnName="true" cachedOnValue="true"/>
         <parameter name="text" value="abc" hidden="false"
             cachedOnName="true" cachedOnValue="true"/>
         <media-type ref="html"/>
         <url cachedOnURL="true"/>
         <category group="Jetspeed">my.portlets</category>
     </portlet-entry>
=============================
the .jsp:
<%@ page language="java" session="false" %>
<%@ taglib uri='/WEB-INF/templates/jsp/tld/template.tld'
prefix='jetspeed' %>
<p>
Shared State Portlet
<br/><br/>
The value of 'text' is: <%= request.getAttribute("text") %>
<form method="post" action="<jetspeed:dynamicUri/>">
<input type="hidden" name="js_peid" value="<%=
request.getAttribute("js_peid") %>">
<input type="hidden" name="action"  
value="portlets.SharedStateAction"/>
<input type="text" name="text" value="<%=  
request.getAttribute("text")
%>" />
<input type="submit" name="eventSubmit_doUpdate" value="Change"/>
</form>
</p>

=============================
the action:
public class SharedStateAction extends GenericMVCAction {

   protected void buildNormalContext(Portlet portlet, Context  
context,
RunData runData) throws Exception {
     HttpServletRequest request = runData.getRequest();
     request.setAttribute("text",
portlet.getPortletConfig().getInitParameter("text"));
   }
   public void doUpdate(RunData runData, Context context) {
     // would like to do this but context is always empty so where is
the Portlet?
     //PortletConfigState.setPortletConfigParameter(portlet, "text",
runData.getRequest().getParameter("text"));
     PortletEntry entry =
(PortletEntry)Registry.getEntry(Registry.PORTLET,  
"SharedStatePortlet");

entry.getParameter("text").setValue(runData.getRequest().getParameter 
("t
ext"));
   }

}
