ODE1X critical sections in bpel

[Rafal Rusin <ra...@gmail.com>]

Hello,

I'd like to have a critical section in bpel. I saw there's no support
for construct <scope isolated="yes"> in ODE1X.
Are there any implementation obstacles for implementing it?
Or maybe there is some other way of doing critical section. I saw
atomicScopes are implemented in ODE1X. But as I read, they are just to
execute some work in transaction, which may be concurrent. So this is
not a critical section. But maybe there is some way?

Actually, one solution is to add active waiting and global variable, like this:

$entered = false

while not $entered {
wait some time
}
$entered = true
some work..
$entered = false

I wonder if there is something better.
