JagDisallowCommit

Description

Indicate that the current transaction cannot be committed because the component’s work has not been completed; the instance remains active after the current method returns.

Syntax

void JagDisallowCommit();

Usage

JagDisallowCommit specifies that the component instance should not be automatically deactivated after the current method completes. If the instance is deactivated before the next method invocation, the current transaction is rolled back.

When a method calls JagDisallowCommit, the component instance is not deactivated until one of the following happens:

JagContinueWork and JagDisallowCommit allow components to maintain state between method calls (using JagGetInstanceData and JagSetInstanceData). If a component is not transactional, JagContinueWork and JagDisableCommit have the same effect: both prevent immediate deactivation of the component.

If a method calls none of JagCompleteWork, JagContinueWork, JagDisallowCommit, or JagRollbackWork, the default behavior is that of JagContinueWork.
