Re: [Trinidad] ConcurrentModification

Rate this Message:
Are you using client or server side state saving?
If client, are you using real client side state saving or Trinidad's
default fake client side state using tokens?
Do you have the trinidad cache view root setting enabled?
It looks like both windows are using the same component tree, which is
bad, I dont think that should be happening. I always turn off
Trinidad's view root caching. It is nice for perf. but can be really
bad for bugs.
