Hi all,

I'm having some issues with service scoping. I'll try to describe my
situation the best I can. If something is not clear, please tell me :).

Having this base classes:

, Module (which can have services)
. Service (which can have other services)

I could have something like this:

UserModule has a UserService, which can have a ContactInformationService.
ContactInformationModule has another instance of ContactInformationService.

So, for the first case, I define in the DIC a "user_module" service, a
"user_service", and a "contact_information_service". Then, in the
"user_module"'s definition, I add the "user_service" to the "user_module"
with a call to a Module's method called "addService". Finally, in the
"user_service"'s definition, I add to it the sub-service
"contact_information_service" with a call to the method "addService".

My problem: Each Module should be instantiated only once. This is OK. But
each Service should be instantiated once per Module and each time it's been
added to a service, as a sub-service. This is because each service can have
a different state, depending on if it's a subservice or not. So, I tried to
change the scope of my services to "prototype" to accomplish this. But then
I received the following error:

*"Scope Crossing Injection detected: The definition
"module_manager.module.user" references the service
"module_manager.module.user.service" which belongs to another scope
hierarchy. This service might not be available consistently. Generally, it
is safer to either move the definition "module_manager.module.user" to scope
"prototype", or declare "container" as a child scope of "prototype". If you
can be sure that the other scope is always active, you can set the reference
to strict=false to get rid of this error"*

I tried to use strict="false" but then I've got an infinite recursion
problem.

Is my approach correct in terms of the DIC? I mean, is it possible to have,
in one hand, one service with scope="container" and add to it services with
scope="prototype" and, in the other hand, have a service with
scope="prototype" and add to it another service with the same scope?

I hope I'm clear. If not, please tell me.



Thanks!
