Lukasz Lenart resolved WW-5312.
-------------------------------
Resolution: Fixed
> ExecuteAndWaitInterceptor inconsistent wait processing behaviour
> ----------------------------------------------------------------
>
> Key: WW-5312
> URL: https://issues.apache.org/jira/browse/WW-5312
> Project: Struts 2
> Issue Type: Bug
> Components: Core, Core Interceptors
> Affects Versions: 6.1.2
> Environment: Java 8, Tomcat 8.5. The behaviour will likely be the
> same for other Java/Server combinations.
> Reporter: James Chaplin
> Priority: Minor
> Labels: pull-request-available
> Fix For: 6.2.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> The _ExecuteAndWaitInterceptor_ processing appears to only execute as
> expected for the first run-through for any given session.
> This can be seen interactively using the Struts2 Showcase "_Execute and Wait
> Examples_", with the wait processing only functioning during the first
> attempt through each example in the same session. Clearing the session in
> the browser gives the expected wait behaviour again, but only one time (until
> clearing the session again).
> After debugging the _ExecuteAndWaitInterceptor_ flow, it appears that the
> removal from the _SessionMap_ did not perform as expected, resulting in a
> state divergence with the underlying session.
> A PR that attempts to fix the behaviour will be submitted soon.
