Hi Howard, So it seems my question was not as stupid as I suspected when I wrote it ;-) OK, I will try to find something else for my events, I don't know what yet; actually, the events notification that I have planned for my service is not used yet (contrary to the famous YAGNI rule) but I suspected I would need it in just a few days. I hope I can figure out some solution to circumvent this problem.
Thank you very much indeed for avoiding me a probable long night of debugging :-) Cheers -----Original Message----- From: Howard Lewis Ship [mailto:[EMAIL PROTECTED] Sent: Monday, October 18, 2004 11:32 PM To: [email protected] Subject: Re: event producing services and threaded or pooled model This is something I've thought about as well, and don't have an easy solution for. I think, perhaps, a proxy should be set up and that should be the listener. The proxy will delegate to the actual, per-thread, service. The problem is ... there's a tangle between ServiceModel and ServiceImplementationFactory (specifically, the BuilderFactory implementation) on who'se responsible for this. I believe I'll have to add methods to ServiceModel to control this, and have BuilderFactory merely identify which services/listeners should be connected. ServiceModel can decide how to procede. So it's doable, but will take a bit of work. With the current code, I'd simply say ... don't do it!
