Adding a Link with a Transition Condition

Adding a Link with a Transition Condition

Add a link with a transition condition based on the completion of the source activity. The condition must evaluate to a Boolean true before the target activity can begin.
  1. Complete the steps for drawing a link, described in
    Adding a Link with no Transition
    .
  2. Select a link and double-click it. Alternately, in the Properties view, click the
    Dialog (...) Button
    next to
    Transition Condition
    .
  3. Build an XPath (or other language) expression, as described in
    Using the Expression Builder
    .
    The following illustration shows an example of condition that prevents an activity from executing if an amount is too large.

In this example, the parameters refer to a BPEL process variable holding data from a WSDL message. For more information, see
Using Variables
.
Linking Activities
You can link any two activities; however, you should use a gateway to clarify the intended purpose of linking. In the following illustration, the construct on the left shows using a gateway and adding a label to describe the transition condition on the link.
On the right side, is a receive linked to two activities. Note that a transition condition is indicated by a mini-gateway diamond; however, you can add a label here as well.
