How to Add an Expression

The Expression Builder dialog shown in Figure 54-10 enables you to create an expression for tracking.

For more information, see Building XPath Expressions in the Expression Builder in Oracle JDeveloper.

To add an expression:

  1. Build an XPath expression of an element to track.
  2. Click OK when complete.

Note:

For variables, Expression Builder inserts $in/variablename. If you are using payload arguments in your expression, you must manually update this syntax to $in.payload/variablename. For example:

concat($in.payload/element, '_', $in.payload/element2)
