Gilbert Kwan updated TUSCANY-2256:
----------------------------------
Description:
There are 3 components
- JComponent (composite scope)
- KComponent (stateless scope)
- LComponent (request scope)
When the composite runs, composite scope service JComponent kicks off a timer
by the @Init method. The timer triggers JComponent every second to invoke a
method that calls an operation on the reference to a stateless scope sevice
KComponent. KComponent calls a request scope service LComponent multiple times.
We found that there was only one instance of LComponent be used and the state
was also preserved. Although it was declared as a request scope service, it
worked like as a composite scope service. (See the attached powerpoint.)
The "SCA Java Annotations And APIs V1" specification line 292 to 293.says, "...
the lifetime of the request is implementation dependent.".
