Hi,
It's indeed a nifty snake you get when using chaining. However, if you
are not returning value there is no easy way of checking if a given call
was successful or not. Of course, you can work it out by building
last-call-error-code variables. Even if at the moment QX chooses not to
return anything, if it needs to later, the future releases could be
incompatible with "chaining versions".
Looks like -1 from me ;-)
Best,
