Hi Chuck!
You might want to simulate this using an attribute with write format
that contains SQL to do this. E.g. something along the lines of
"COLUMN + %V"
In your code you would set the special attribute's value to the
increment you want. On the next commit it would do the stuff.
The problem is that your real attribute would go out of sync and that
your fake attribute would apply the increment on each commit.
You could also try dynamically adding the attribute in an editor to
the editing context and remove it once saveChanges went trough.
Best,
Pierre

I recall someone making something that did this, but now I can't
find it. I don't even recall how it worked. What it did was
allow WO to update an attribute of a entity using bar = bar + 1
instead of bar = 7 so that updates from multiple sources would not
step on each other.
Does this sound familiar to anyone?
Thanks!
Chuck
