[jira] Updated: (WW-2392) Handle additional actionName formats for ActionChainResult

["Richard T. Feak (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/struts/browse/WW-2392?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Richard  T. Feak updated WW-2392:
---------------------------------

    Attachment: SmartActionChainResult.java

It's not a patch or test, but may assist in moving this forward.

Here's the implementation that we are currently using to solve this issue. It's based on the 2.0.11 source of ActionChainResult. There are basically a dozen lines of code added at the beginning of the execute() method (other then the class rename). The goal was to add the functionality without changing the original interface. This enhancement should *not* break backwards compatibility at all.

Thanks for the consideration.

> Currently it's simple to define a chain result for an action in the same package, with a method of execute(). However, to chain to an action in a different namespace, or a method other then execute() requires additional XML markup that seems unnecessary.
> We already have a defined string format for referring to namespaces and methods. Could we use that format to simplify the definition of chain results?
> For example:
> <result name="success" type="chain">foo!bar</result> - Should refer to the bar() method in action "foo" in the same namespace.
> <result name="success" type="chain">/foo/bar</result> - Should refer to the "bar" action in the "foo" namespace
> <result name="success" type="chain">/foo/bar!baz</result> - Should refer to the baz() method on the "bar" action" in the "foo" namespace.
> As you can see, this format is much more intuitive and concise when compared against the current syntax for defining chain results.
> I'm assuming that somewhere there is common code for parsing such strings. it should be easy to re-use that code to prepopulate the variables in the ActionChainResult correctly.
