Arrrghh!!

OK, here it is: In order to be able to run isolated forms and processes during development (and for safety-reasons during runtime), most of my classes and forms check if everything is as they need it. There is an Application-Object, a global Eventhandler, one or the other procedure that needs to be set in order to run everything smooth.

so there is a call like

do CheckEnvironment in PROC_SCHEDCUST.FXP  && <-- Don't want to check wether the proc. is set, so call
                                           &&     the method directly with the IN clause.

and this of course does something like

if type("goApp") # "O" or isNull(goApp)
    public goAPP
    goApp = NewObject(ccApplicationClassName, ccApplicationClassLib, "", gc_ThisINI)
endif

!BINGO!
In "real life" in the EXE this actually never happens as this stuff is checked and created from the main prog and therefore in DataSession 1.

Interestingly enough, although the App-Object for instance is NOT a session it still runs in the session it's been created in, even if the form that caused the "trouble" is gone for ages - just as You already mentioned it with the SCATTER MEMVAR NAME.

Not really surprising if You think of it, but!, You need to think of it to avoid it ;-)

I added a small method to the application-Class, that shows the effect.

PROCEDURE MySession
    acti screen 
    ? "Hi, My name is "+ this.Name +" and I am currently working in Datasession "+ trans(set("Datasession"))
ENDPROC

BTW, in contrast to Dangling References, releasing the affected Objects will properly close the "Dangling Datasession".

For all the others, that possibly but hopefully never trap into this, here the solution:

Put your global stuff into a Method that checks the current DataSession and if necessary changes it to 1. At the end reSet it to the correct DS.

Something like this

LOCAL lnWasSession

lnWasSession = set("DATASESSION")

if lnWasSession # 1
    *acti screen
    *? "Session: ", lnWasSession
    set Datasession to 1
endif

if type("goApp") # "O" or isNull(goApp)
    public goAPP
    goApp = NewObject(ccApplicationClassName, ccApplicationClassLib, "", gc_ThisINI)
endif

....

*-- and ReSet the DataSession
set Datasession to lnWasSession
return .T.

Thanks for giving me a hand on this.
