Rajeev kumar commented on WW-3488:
----------------------------------
Attached patch is working fine, but here still result is null. The main change
you have done changed 'and' ('&&') condition with 'or' so it is working fine
with result 'null' case also.
- return result != null &&
ActionChainResult.class.isAssignableFrom(result.getClass());
+ return root.size() > 1 && (result == null ||
ActionChainResult.class.isAssignableFrom(result.getClass()));
> ChainingInterceptor doesn't copy the value stack to the target action

> Key: WW-3488
> URL: https://issues.apache.org/jira/browse/WW-3488
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.2.1
> Reporter: Mika Laukka
> Assignee: Lukasz Lenart
> Fix For: 2.2.2

> This can be easily reproduced by running the bundled struts2-showcase web
> application.
> http://localhost:8080/struts2-showcase-2.2.1/actionchaining/actionChain1!input.action
> results in this:
> Action Chain 1 Property 1:
> Action Chain 2 Property 1:
> Action Chain 3 Property 1: Property set in Action Chain 3
> So clearly the properties set in action 1 and action 2 are lost in the
> chaining process.
> For comparison, version 2.0.14 output
> http://localhost:8080/struts2-showcase-2.0.14/actionchaining/actionChain1!input.action
> results in this:
> Action Chain 1 Property 1: Property Set In Action Chain 1
> Action Chain 2 Property 1: Property Set in Action Chain 2
> Action Chain 3 Property 1: Property set in Action Chain 3
> Which is the expected result. This bug may be related to fixing of WW-2869.
