Wildcard Mappings, Last one loses.
----------------------------------
Key: WW-3464
URL: https://issues.apache.org/jira/browse/WW-3464
Project: Struts 2
Issue Type: Bug
Components: XML Configuration
Affects Versions: 2.1.8.1
Environment: OS X 10.6.4, Java 5, Running from inside Netbeans using
embedded tomcat
Reporter: Robert M. Zigweid
Given the struts.xml snippet:
<action name="*" method="{1}" class="web.BaseView">
<result name="success" type="tiles">Welcome</result>
<result name="test" type="tiles">test</result>
</action>
<action name="Project*" method="{1}" class="web.ProjectView">
<result name="none" type="tiles">NoProject</result>
</action>
I generate the log results as follows:

As you can see the "*" is matched as opposed to "Project*", which seems to go
against the
'last one wins' as is described by the struts documentation on
http://struts.apache.org/2.1.8.1/docs/wildcard-mappings.html
Now, if I reverse the order of the actions in struts.xml I get the following
result:

Here, the "Project*" action is being matched as opposed to "*" despite being
first.
I'm failing to see how 'last one wins'
