Re: Context-#session

The problem that I have is that pier saves its history by saving its instances of PRContext', namely the context of the model changing command being performed. This context happens to have a local cache in it's properties the seaside session ('to avoid unneccessary lookups'), which if it is WAMagmaSession has a magmaSession instance var. Now I could attempt to clear this cached value out before persistence takes place, but I see no guarantees that some other bit of code may reference the session and repopulate the cached value while I am not looking.

In trying to implement MagmaPersistency it turns out that the fact that PRContext holds a local cache to the current session may be a bit of a pain. Not only may there be a lot more stuff accidentally persisted through this reference, there may actually be objects that magma gurus say 'don't persist these if you know what is good for you'. I cant see that this cache is widely used, so I wondered if anyone would object if it was removed i.e. make this method lookup the current session the hard but not all that slow way (about 100 microseconds, on my oldish 700Mhz machine) PRContext>>session ^ WACurrentSession value any thoughts/opinions?
