To Set Mule Expression Watches

To instruct Studio Debugger to watch for an expression:

  1. In your Expression Watches View, click the Add Expression add-icon icon.

  2. The debugger prompts you to enter the new expression for which to watch.

  3. Studio displays the new Watch in the Mule Expression Watches View. If your expression is a declaration, the debugger returns a boolean; if not, returns the value. For example:

    • The expression message.payload == 'myPayload' returns either true or false.

    • The expression message.payload returns the value of message.payload.
