Subject RE: Custom action mapping / or configuration of actions....
Date Wed, 29 Dec 2004 23:29:05 GMT
Finally I had time to isolate the issue. The thing is that if you define
global action mapping in <action-mappings> and use multiple config files
(all in one module) the actions in config files that are processed later
will keep global setting from previous config file (unless you overwrite
the global setting).

More detail, example and patch are in bugzilla:

Ah... so you have to tell Struts to use your custom subclass.  This 
can be done for a single element using

<action className="com.example.MyActionMapping" ...>

or if you want to use it for all action mappings,

   <action-mappings type="com.example.MyActionMapping">

Note that I think there's a problem where if you use a custom 
action-mapping in the <action-mappings> element and you use a list of 
struts-config files, the value has a wider use than you'd expect -- I 
believe someone on my team told me that it also applied to action 
mappings in other struts config files which were processed later. 
You'd expect it would only apply to the action elements which are a 
child of the action-mappings element where that value is declared. 
I'll ask him to confirm and file a bug if that's true...
