RE: [wsrp-wsia] [I#184] can performInteraction return new navigationalState?

[Gil Tayar <Gil.Tayar@webcollage.com>]

I submit that it performInteraction shouldn't return new navState. It all comes back to the two things that differ between performBlockingInteraction and performInteraction:

 

1. In performBlockingInteraction, the Consumer cannot return anything to the client, as the Producer may request a redirect  - either directly using redirectURL or indirectly (for some Consumers) by changing the navigationalState or the window state.

2. In performBlockingInteraction, the Consumer cannot call other getMarkups until this call returns, as there may be side-effects.

 

In the F2F, I wanted two flags to separate these two "blocks" but it was felt (and I believe rightly so) that this would complicate things. It was believed (and rightly so) that the optimizations gotten by separating these two cases would not justify the complexity cost in understanding v1.0.

 

That is why I to make things simpler, v1.0 must not make the distinction between the two. This will make creating Producers simpler and more understandable (actually, this is the road I take in the Primer).

 

That is also why to make things simpler, v1.0 Producers must not try and understand the distinction between Consumers -

1. Those that use their URL to store the Producer's navigationalState, and those that don't.

2. Those that need to show a different page in response to a windowState change, and those that don't.

 

It should state clearly - the Producer must accomodate both by assuming that Consumers need redirects on response to a navigationalState/windowState change, and thus using performBlockingInteraction. The optimizations gotten by not doing this would, IMHO, bot justify the complexity cost in understanding (and implementing) v1.0 Producers.
