Noun-Verb Object Erase

[SRSDS]

I need to review entities before erasing them.

I was assessing entities in the CommandWillStart and finding associated objects

In CommandWillStart I collected any associated objects via their Xdata.

In the CommandWillEnd Event I dealt with their associated objects.

Then I realized there was a Noun-Verb Object Erase. (Where the user entered the Erase command then selected objects.)

I could use an Erase ObjectOverrule but that would need to open and close a Transaction for each entity to review it's Xdata. Would this slow my app down? Or is there more sensible alternative?

Maybe watch for the Object.Erased event and unerase as necessary.

I think I understand the problems I've been having

A)

I don't need a transaction to read xdata in db.ObjectErased

Dim myXdata As Array = e.DBObject.GetXDataForApplication(AppName).AsArray

B)

Even if I did I was having problems when I was using .StartTransaction when I should have been using .StartOpenCloseTransaction

Thank you. That pointed me in the direction I needed to recap my memory.
