Description copied from interface: IWorkflowTaskRunner

Executes the given workflow tasks triggered by an event, and returns the result. Each task is run to completion, irrespective of whether other tasks have completed successfully or erroneously.

If any node throws an unhandled exception, it will be converted to a WorkflowProcessingException. This method guarantees that each results in either a ITaskExecutionSuccessResult, or a ITaskExecutionErrorResult.

This method creates a new entity context to access the database. Make sure to reread the relevant entities after a call to this method.

Specified by:

runTasksForEvent in interface IWorkflowTaskRunner

Parameters:

runTasksParams - The task to run, and optionally an entity context to use.

Returns:

The result obtained after the task was executed normally.

Throws:

CouldNotLockFormRecordException - When no lock could be acquired on the Vorgang to process. Only one task of a form record can be run at a time.
