Dan Haywood commented on ISIS-620:
----------------------------------

Just to restate the scenario (I had to read it a couple of times to get it):
a. the user is working with some entity, eg Order
b. they realise they now need a Product to complete what they were working on, 
which they do, using Products>newProduct, and end up at the Product entity
c. they now press back button to get to step (a), whereupon
d. they get a concurrency exception when they interact with the Order.

Some further ideas:
4. if the concurrency exception is because of the same user, we could ignore 
"sven attempted to update TODO:L_23, however this object has since been 
modified by sven at Mon Dec 02 18:13:13 CET 2013 [3 vs 2]"... if it was 
modified by sven and sven is updating, then let it through
5. when go back to entity, do a proactive check to see it is stale, and reload 
if necessary.  Not exactly sure how to do that, though.
