RE: consumer registration

[Tali Garsiel <tg...@mercury.com>]

Hi,

I'm currently trying to support the following configuration:

My portal - using wsrp4j is the producer

WebLogic is a consumer

A funny thing happens -

WebLogic seems to think that once he got a cloned portlet he should stick
with it.

We on the other hand - clone the portlet on every state change and give the
new handle in the blockingInteraction Response.

WebLogic ignores it! And asks the markup for the old handle!!!!

According to the spec it seems that we are right - but that means no support
for at least one big portal!!! 

Any help will be appreciated!

Thanks, Tali

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.
