RE: [wsbpel] Issue - 151 - Allow a new process instance to be created by "pick onAlarm until"

["Satish Thatte" <satisht@microsoft.com>]

I don't get the use case.  No one is going to deploy a process to be activated only once at a specific time.  This defeats the whole notion of activation -- you might as well start a daemon using some other scheduling mechanism in the deployment environment.
 
Also agree with the comments by Yaron.

I just wanted to go on the record as saying that I believe this feature
is an issue for deployment/configuration and therefore out of scope for
BPEL. I want to echo Ron's comments that process designers more often
than not are not in a position to know what actual values should be used
and therefore this is something that should be set at deployment time by
the deployment admin.

                Thanks,

                        Yaron
