Cassy,
If your page flow looks like this:
first.jsp -> actionA(FooForm) -> second.jsp -> actionB()
Then I think the problem is that there is no action form in scope as
second.jsp is rendering. This is because the action raised by
second.jsp is actionB, which has no form, and hence no {actionForm}.
You have two options:
Option A - use page inputs (available in the upcoming Service Pack 2)
---- JSP:
<%-- At the top of your second JSP... --%>
<netui-data:declarePageInput name="myPageInput" type="APageInput"/>
<netui:label value="{pageInput.myPageInput.name}"/>
---- JPF:
* @jpf:action
* @jpf:forward name="success" path="second.jsp"
protected Forward actionA(FooForm form)
APageInput input = new APageInput(form.getName());
return new Forward("success", "myPageInput", input);
Option B - since the form is still technically in the request, use it as
a workaround until option A is available to you.
<netui:label value="{request.fooForm.name}"/>
I hope this helps.

Cassy--
Is there a <netui:form> tag on the page which displays this error
(pageB.jsp?)?
The "actionForm" binding context can only be used inside of a
<netui:form> tag. To display data in a read-only page (no form), you
can put the data in the request and reference it with the "request"
binding context.
Hope that helps...
