consumer registration
Hi,
I'm new to WSRP (and portal technology)
I have the following problem:
My portal is a producer using wsrp4j.
I set registration requirement to false.
The consumer sends me empty registration context.
When I get a performBlockingInteraction request I get an exception because:
The portlet instance is ProducerOfferedPortlet
function handlePortletStateChange (WSRPEngine class) calls clonePortlet
clonePortlet fails because I have no registrationContext (line 1174 -
"String regHandle =
request.getRegistrationContext().getRegistrationHandle();)
I want to know
Is it a bug ? or should I require registration ?
Thanks, Tali

This is a bug because a clone should be allowed even when registration
is not required. The clone should be scoped by a "null" registration.

A clone can't happen without a registration context. The question is
why is the portlet getting cloned?
I looked at the code, and there is some handling in
performBlockingInteraction which checks the portletStateChange flag.
Oddly, if the portletStateChange flag is readOnly, then it tries to
clone the portlet. This doesn't seem to make sense, but there is a
comment which suggests that this is necessary because of JSR168
portlets. This is going to take more research, but it looks like a bug.
However, looking at the code, if you set the portletStateChange flag to
readWrite, it will make it through PBI without getting cloned. I guess
you could try this.
