Using the Expression Builder

Using the Expression Builder

Select from the Variables, Functions, and Operators pick lists to create an expression in the Expression/Condition text box.
You can select among the many function types to create an expression for Copy Operations, link transitions, and other BPEL constructs. See the procedure below for details on building an expression.

  • Select Expression Language
For Copy Operations in the Assign activity as well as for links and other constructs, you can create XPath (or another selected language) expressions that result in a string, number, or Boolean.
For details, see the XPath 1.0 specification at
http://www.w3.org/TR/xpath.
To build an expression:
  1. Select an activity that uses expressions, such as the assign, wait, or on alarm branch of a pick activity.
  2. In the Properties view for the activity, select the appropriate property. For example, in an assign activity, select Copy Operations, and select Expression as a Copy/From type to display the following dialog:
  3. Select the variables, functions and operators from the three boxes to build an expression, following these tips:
    • Build expressions faster with shortcuts. See
      Using Content Assist
      .
    • Expand a variable to see and use the parts and properties. For detailed descriptions of variables, see
      Using Variables
      .
    • Select a variable, part, function, or operator and select
      Insert
    • For working with variable attachments, see
      Custom Functions for Manipulating Attachments
      .
    • Add your own custom functions, as described in
      Creating POJO and XQuery Custom Functions
      .
  4. Select
    Evaluate
    to substitute a sample value for a variable part and simplify the expression to view its value.
