Here's a fix for "This item cannot be updated because it has been changed by another user or process"

Question

https://gallery.technet.microsoft.com/System-Center-Service-fca7af29
A few months ago on the Technet Gallery, I submitted this custom control to be used on SCSM console forms. The purpose of the control is to eliminate the "This item cannot be updated because it has been changed by another user or process" error
message that we all have seen at least once (a day :) ).
The details are in the gallery description (along with installation instructions for existing forms and your own custom forms).
Here's a "short" description (nothing I ever post here is short :) ): This is a custom control that can be applied to an SCSM form like the Service Request form or Windows Computer form or your own custom form built with the authoring tool or Visual
Studio. When you click "OK" or "Apply" on the form, this control scans the form and Service Manager's database for any changes to the object you have open. If a property that _you_ have changed on the form was _also_ changed in the CMDB
(by a workflow or another user), this control will present a dialog box letting you know what happened. It will also let you choose which value to keep (yours, theirs, or the original value).
Just as importantly (and important in a greater percentage of cases), if a workflow changes a "background" property (like FirstAssignedDate) while you have the form open and you click OK, the control will detect the change and allow the form submission
to go through while keeping your changes and the FirstAssignedDate change that the workflow made. You won't get an error message or even a warning. And most importantly, you won't lose your changes.
That's where the "optimistic" part of the control's name comes from. It applies optimistic concurrency control to SCSM forms, while also providing an anti-collision interface for you to use so you no longer lose any of your changes.
Furthermore, this control will work on related items that are opened in memory; for example, the activities on a Service Request. So if you change an activity's title while the workflow engine sets it in progress, you won't get an error. The activity will
be in progress and will get your new title when you click OK or Apply.
Lastly, (and I admit this part is getting into the deep inner workings of console forms) if your form loads a sub projection at run time (to the root object) this control will detect the load and treat that sub projection as if it were apart of the original
form all along.
I've gotten a little feedback about this control, but I'd like to get more since it's a work in progress. So, I'm announcing it here on the forums. Please give it a try and let me know if you have any questions. I'll be happy to answer them here. Thanks,
folks!
Oh, and to answer the most common question right away: It's free. There is no paid version or anything like that. This is something I built for the SCSM community.
