Hi Mustafa,
I think you're using pre and defer for the wrong purposes. For what
you describe here, inherits is much more appropriate and will only go
to the child once you explicitly call the child() method or a child
trigger succeeds. I wouldn't use pre and defer at all in these cases.
Hope this helps,
Geert

Hi,
The defer problem is not only about PRE element. In my case, I have
a PRE element which checks if there exists any locks in my server
or not. If I have any locks in serverside I want to give user a
message that "Server is unavailable." error message for some
requests. For this purpose I designed an element which only checks
existancy of the lock and if any lock exists print the error
template and defer . By this way, I tried to interrupt execution of
the following element. I know there are some other ways to do this
like by using flowlinks etc, but I thought that the simplest way is
using a pre element.
The second problem about defer is that I extended rife
authentication and authorization mechanism for several puposes
(such as multiple role support, sub application authorization
mechanism, and etc.). As you know Rife doesnot differentiate
whether user request rejected because of authentication failure or
authorization failure. It gives the same error message that invalid
credentials for both cases. Therefore, user is unable to check
whether its password or username is wrong or he cannot access this
part of page. I changed the authentication and authorization logic
for this purpose. I print authorization error template and after
that used defer to cancel execution. In this case again I faced
with illegalstateexception.
