No, actually it belongs on the user list.

When you say "after several forwards", do you mean you are chaining
actions? That is, forwarding from one action to another? If so, the
problem you are seeing is an inevitable consequence of that, which is
why chaining actions is strongly discouraged.
Instead of chaining Actions, you should be delegating from your (one)
Action to your business logic. One option, if you really need a chain,
is to use the ChainAction class from the Struts Chain package (in
contrib), and implement each of the pieces of the chain as a Command.
