[Esml-users] Re: RE Esml-users Event ports with null event refs

[Jesse Greenwald]

Hi Sandeep,

After looking at OEP Rose model and the XML ESCM export, I think there
are some problems with the model.  For instance, there three different
event types for timeouts (Interval Timeout, INTERVAL_TIMEOUT,
INTERVAL_TIMEOUT).  Shouldn't these all be the same?  There should also
be an event type for data available events since this is the other event
type that is used in the system.  Instead, there is no data available
event and components are being specified as just publishing ANY.  But,
this would seem to imply that the components are publishing timeout
events, but only timers should be publishing timeout events.

I'm going to go ahead and ping the Boeing folk and see what they say
about the model.

Thanks a bunch for help,
Jesse
