David updated WW-2970:
----------------------

    Attachment: chainapp.zip

The attached sample webapp demonstrates a problem with action chaining in Struts 2.1.6 using WebLogic server.  A parameter set on an action class in struts.xml is re-set on the chained action, thus overwriting any values set in other action classes earlier in the chain.

Below are steps to reproduce the issue.

Setup:
1)  Unzip chainapp.zip
2)  In build.xml, modify the following properties:
  -wls.lib.dir
  -wls.serverName
  -wls.hostname
  -wls.port
  -wls.username
  -wls.password

Test 1 (using Struts 2.1.2, to show expected/correct behavior)
1)  Run the ant task "deploy"
2)  Open a web browser to http://localhost:<port>/chainapp/chainTest
3)  Check stdout, you should see the following:

Action1.execute()
Action1.execute() : getPageName() = InitialPagename
Action1.execute() : getPageName() = PageNameFromAction1
Action2.execute()
Action2.execute() : getPageName() = PageNameFromAction1


Test 1 (using Struts 2.1.6, to demonstrate the bug)
1)  Open resources/pom_ChainTest.xml
2)  Comment out the section titled "Struts 2.1.2"
3)  Uncomment the section titled "Struts 2.1.6"
4)  Repeat steps from Test 1
5)  Check stdout, you should see the following:

Action1.execute()
Action1.execute() : getPageName() = InitialPagename
Action1.execute() : getPageName() = PageNameFromAction1
Action2.execute()
Action2.execute() : getPageName() = InitialPagename

> If a param is set on an action in a chain through struts.xml, it will be set on all subsequent actions in the chain, thus overwriting any values that may have been set by the actions themselves.
