All - We represent discovered cross bore locations as simple point features in our current gas distribution ArcMap/GN implementation.   I don't see a direct correspondence in the UPDM - but I may be missing something. Any guidance/suggestions here would be much appreciated. Thx, Ed ... View more

Hi all - In our current implementation use use several "static" versions to assist with Geodatabase change detection.  For example, there is a nightly process that compares a static version with SDE.Default to determine which feeders have changed in order to inform the OMS interface which feeders need to be extracted and updated in the OMS database. There are other static versions for other, somewhat similar purposes. For OMS we might be using ArcFM GDBM/Feeder Services to detect changes.  But for other, non-feeder change purposes, we're wondering if we need to keep static versions around. Any thoughts/experiences on this would be much appreciated. Thanks, Ed ... View more

I've been trying to figure out, without success, how to present a form to a user from within a handled edit event.  An example use case would be a user places a feature in an unexpected location and we want to present an "Are you sure?" message.    Is this possible?  If so, any pointers would be appreciated. Thx, Ed ... View more

Hi - The code below attempts to create an association between two utility network features within a HandleEditCompletedEvent.   As it is, it consistently throws an error when attempting to add the association, line: _un.AddAssociation(assoc) The error message states that "This task must be performed within an Edit Operation" - but the AddAssociation *is* performed within an edit operation. Now, it may be that what I'm trying to do -- perform an edit to create an association within an edit event fired on creation of a feature that would be part of that association -- is just not supported.  But that's not what the error says. Anyway, any guidance on this would be much appreciated.

In our current 10.x world we make significant use of ArcFM AutoUpdaters to perform important business logic (like many utilities). We're implementing the UN and now considering how to replace that logic.   (Quite a bit is not accounted for out of the box.) On the one hand it seems that ArcFM XI supports handling of edit events on feature services through their Server Object Extension -- though I don't at the moment know how extensible this is. One the other hand ArcGIS Pro exposes Edit Events, not unlike the way ArcMap does, which we could handle to provide similar capabilities to what we have now. I'm *very* curious to hear thoughts from others who have already gone down this path. Thanks in advance for any feedback. Ed   ... View more
