I think what jeremy meant is that if you add a mutable object (like a bean with
setters and getters (or a list but see below)) to the exchange before the
multicast, each of the exchanges in the multicast will be shallow copies of the
original exchange, this means that they will all contain this object (the same
instance). This means that it is possible to have some common data in the
exchanges for that. However if the multicast is parallel (multiple threads) all
the methods you are calling in the multicast must be thread safe (which is not
the case for normal list objects).
The common bean approach does of course also work, but here you have one bean
per camel-context, which means that all invocations of the route will share the
data (which may or may not be what you want).
Best regards

Subject: Re: sharing exchange properties in mutlicast route
The Exchange properties won't be visible as the sub-routes would have different
exchange objects.
I have verified this by checking the exchange IDs and they were different in
each sub-routes..
The exchange properties set in one sub route when accessed on other sub-routes
returned null.
am I missing anything?
As suggested by Claus, I created a common bean to store the data required,
which I am accessing in each of the routes.
