Creating a Join Condition for an Incoming Link
Set a join condition to evaluate the success or failure of incoming links. A join condition is a Boolean expression indicating the status of a link targeting an activity.
When one or more links are connected to an activity, you can set a join condition to evaluate the success or failure of the incoming links. A join condition is a property of all activity types and allows you to construct complex execution conditions based on link status. For more information, see Using Links.
When the join condition evaluates to true, the process continues normally. When a join condition evaluates to false, the process can throw a joinFailure fault.
If you set the suppressJoinFailure property to yes for an activity that has a join condition, it means that a false join condition will not throw a joinFailure fault.
To create a join condition:
- 1. Display the Properties view of an activity with an incoming link.
- 2. Select the Show Advanced Properties button to display all properties of the activity.
- 3. Click the Dialog (...) Button next to Join Condition to display the following dialog.
- 4. Double-click a link to paste the BPEL link status function into the Join Condition box.
This function returns a Boolean indicating the status of the passed link.
- 5. Click OK.
