[AG-DEV] AG3 Shared App Migration - EventID

[Thomas D. Uram]

Todd:

Before 3.0.2, event.GetSenderId will return the private id of the user,
which changes with each entry into the venue, or join to an application;
with 3.0.2, event.GetSenderId will return the public id of the user.  This
is an inconvenient but necessary change.  If you need to compare
the senderid against the local user's id, I'd suggest you compare
event.GetSenderId against SharedAppClient.eventClient.id, which will
work correctly in either version.

If this suggestion doesn't address the problem you're running into,
let us know.
