essentially we like to do 2 things with exceptions:
1) render "inline", eithier as a comment string, or as somthing informative
for the user.
2) abandon the merge and do something appropiate depending on the exception
an example of practical usage is if you have an object in your context that
has a property with restricted access.
1) you may want to nicely hide the restricted property: "sorry, you are not
allowed to view user's passwords"
2) or you may want to redirect the user to a login page

umm, i had trouble getting merge time exceptions out, i could only get a
MethodInvocationException (hence the initial post). Perhaps i've missed
something.
thanks for your help
