Description

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:

20676 [http-8084-2] DEBUG com.opensymphony.xwork2.conversion.impl.InstantiatingNullHandler

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:

13176 [http-8084-1] DEBUG com.opensymphony.xwork2.conversion.impl.InstantiatingNullHandler

Here, the "Project*" action is being matched as opposed to "*" despite being first.

I'm failing to see how 'last one wins'
