Hello friends I would like to share scenario
on usage of Shared Business Objects Usage in IBM BPMv8.0
About Shared Business Object:-
Shared Business object values should be accessible to other instances at run time. Shared business objects
only apply to a complex structure type. The data within a shared business object
is shared between business processes and tasks.
A shared
business object uses database resources. The data within a shared object is
persisted to the database when:
- The shared object is created
- The business process or task is persisted to the database
- The JavaScript method save() is performed on the shared business object
Declaring Shared Business Object:-
Example Scenario:-
This Scenario display a employee details on
simple coach .One employee variable is shared Bo type and another one is unshared
Bo type.

Variable declaration in BPD and Human Service:-
Running the Sample:-
Employee HS output:-
This is first coach which is
displaying the default values and click on ok button.Then flow will create a token
on Employee1 (Usertask ) and Employee1(Usertask
) as I used parallel gateway it will wait until two tasks done.
Edit Employee1 HS output:-
Change the values in Enter Last name
field in Employee share and Employee Noshare
fields(i.e D to Dondeti)
Click on Ok button then flow waits at Edit Employee2 HS out put. Run the service.
If you observe the above coach the
value which I changed in EditEmployee1HS is affected to Employee Share BO
because it was shared business object type.
How to initialize and Retrieve a shared Business Object Using
Javascript:-
Ability to explicitly load shared
Business Object if required using theunique key associated with it
• Loading a shared Business Object
tw.local.empShare=
newtw.object.EMPLOYEESHARE(uniqueKey)
• Getting the unique key:
tw.local.empShare.metadata("key")
Example:-
// Create shared object
var empShare = new tw.object.EMPLOYEESHARE();
empShare.lastName =
"Dondeti";
sharedObject.save();
// Create key for shared
object
tw.local.empShareKey =
empShare.metadata("key");
log.info("empShareKey:
" + tw.local. empShareKey);
// Retrieve shared object
by key
var empShare2 = new tw.object.EMPLOYEESHARE
(tw.local.empShareKey);
log.info("empShare2.
lastName: " + empShare2. lastName);
Thanks for reading .I hope this
post helps you. So far this is my best effort to explain. Please correct me if
I do anything wrong.
