The EXIT Step 4 Build the body of the loop using the following steps: a Insert a flow step using the buttons on the editor toolbar. 7. Inserting Flow Steps b Indent the flow step using on the editor toolbar to make it a child of the LOOP step. c Set the properties for the child step as needed. 5 Use the Pipeline tab to link the elements of the input array to the input variables required by each child of the LOOP step. For more information about using the Pipeline tab, see Chapter 8, “Mapping Data in a Flow Service”. Important! When you build a LOOP step, make sure that you specify the output array variable in the LOOP Output array property before creating a link to the output array variable within a MAP or INVOKE step in the body of the LOOP. If you specify the output array variable after creating a link to it, the link will fail at run time. You can test the step in Developer to see if the link succeeds. If the link fails, delete the link to the output array variable and then recreate it. The EXIT flow step allows you to exit the entire flow service or a single flow step. You specify whether you want to exit from: � The nearest ancestor (parent) LOOP or REPEAT flow step to the EXIT flow step. � The parent flow step of the EXIT flow step. � A specified ancestor flow step to the EXIT flow step. � The entire flow service. When you use the EXIT step, you indicate whether exiting should return a successful condition or a failure condition. If the exit is considered a failure, an exception is thrown. You can specify the text of the error message that is displayed by typing it directly or by assigning it to a variable in the pipeline. Examples of when to use the EXIT step include to: � Exit an entire flow service from within a series of deeply nested steps. � Throw an exception when you exit a flow or a flow step without having to write a Java service to call Service.throwError( ). � Exit a LOOP or REPEAT flow step without throwing an exception. The following flow service contains two EXIT steps that, if executed, will exit the nearest ancestor LOOP step. If the value of CreditCardType is null or an empty string, the matching EXIT step executes and exits the LOOP over the '/PurchaseOrdersList' step. webMethods Developer User’s Guide Version 6.5, Service Pack 3 � � � 190

Inserting Flow Steps 1 If you are inserting an EXIT step into an existing flow service, display that service in the editor and select the step immediately above where you want the EXIT step inserted. 2 Click on the editor toolbar. 3 Complete the following fields on the Properties panel: For this property… Specify… Comments An optional descriptive comment for this step. Label An optional name for this specific step, or a null, unmatched, or empty string ($null, $default, blank). Important! If you use this step as a target for a BRANCH step, you must specify a value in the Label property. For more information about the BRANCH step, see “The BRANCH Step” on page 168.
