What could be causing this?
No, the two ec's in your example will properly update (you're not
holding an ec lock across requests, so the first EC is causing the
second EC to update). The easiest way to force an optimistic lock
is to go into your edit form on an EO, and then update the database
manually with SQL commands in the background. This will cause your
snapshot cache to be out of sync. The only way to get it to happen
INSIDE your app would be to have two EC's attempt to change the
value while both are locked.
Or to have each EC created using a different EOF stack. EOF won't
sync across stacks within the same instance (though doubtless Wonder
has something to provide this if desired).
