Skip Condition Tab

2.36 Skip Condition Tab

Use to specify an XPath expression in an activity that, when evaluated to true, causes that activity to be skipped.

The bpelx:skipCondition attribute causes an XPath expression to be evaluated immediately upon creation of the activity instance. If the skip expression returns a false boolean value, the activity is executed. If the skip expression returns a true boolean value, the activity is completed immediately and execution moves to the activity immediately following that one. For example, you may specify an XPath expression such as the following:

"bpws:getVariableData( 'crOutput', 'payload','/tns:rating' ) > 0">

If a value of 3 is returned, the expression evaluates to true, and the activity is skipped.

You can also use built-in and custom XPath functions and $variable references within the skip condition expression.

This functionality provides an alternative to using a switch activity for conditionally executing activities.
