The Stall service provides the execute operation, which is useful for preventing situational errors that you anticipate may occur.

For information about using the Stall service, see Services Reference for Adobe LiveCycle ES4.

execute operation

When used in asynchronous and synchronous branches, the execute operation stalls the branch. If you are aware of a possible situational error in your process, you can add a route that leads to this execute operation. You add a condition to the route that checks if the situational error has occurred. When the situation occurs, the branch is stalled so that you can fix the error and restart the process using the Administration Console.

Note: When used in transactional branches or short-lived processes, the execute operation throws an exception instead of stalling the branch.

For example, processes can use data that is provided from an external resource, such as a partner's database. A Script action can be used to verify that the data is valid. If the data is not valid, a Stall action can be executed that stalls the process instance while the data in the database is corrected.

For information about the General and Route Evaluation property groups, see Common operation properties.
