Description
While it is possible to set the maxConversations property on the FlowExecutor bean (which sets a property of the SessionBindingConversationManager) it is not possible to set the timeoutSeconds which configures the seconds it takes before the LockTimeoutException is thrown. So it would be nice to see something like below:
<webflow:flow-executor id="flowExecutor">
<webflow:flow-execution-repository max-executions="1" max-execution-snapshots="25" lock-timeout-seconds="15" />
</webflow:flow-executor>
The setting of the lock-timeout-seconds attribute will call the setter on the SessionBindingConversationManager in the createConversationManager-method of the FlowExecutorFactoryBean.
With the current build it is only possible to do this programmatically.
Thusly:
SessionBindingConversationManager sbcm=(SessionBindingConversationManager)ExternalContextHolder.getExternalContext().getSessionMap().getAttribute("webflowConversationContainer");
sbcm.setLockTimeoutSeconds(15);

Hey Keith,
Can you take it as major issue. I tried programmatically but it did not work.

Can you take it as major issue. I tried programmatically but it did not work. This solution sets lock time-out in the SessionBindingConversationManager during start-up of application. I hope, the setting will be adjustable in the next release of Spring WebFlow.

} I would think this should have been marked as an urgent issue. Still no hope??

Is there any kind of timeline on a fix for this ? The system I'm working on unfortunately has some long operations that we've been unable to shorten and increasing the lock timeout would be a great help.
