[jira] Resolved: (WW-2082) Result annotation for StreamResult uses value tag instead of inputName parameter for the name of the stream property

Don Brown resolved WW-2082.
---------------------------

    Resolution: Fixed
      Assignee: Don Brown

Actually, it turns out, they are the same thing.  The "value" attribute in the Result annotation, known in the XML config as the default parameter for a result, sets the 'inputName' parameter.  Therefore, when you define both the 'inputName' and the default parameter, the regular 'inputName' is processed first, then the default parameter is processed, overwriting the specifically named parameter.  

We could switch this, however, it would cause an issue for backwards-compatibility.  I'd rather just update the docs to clarify how the default parameter works.  I've updated the result types page: http://cwiki.apache.org/confluence/display/WW/Result+Types

> The documentation for StreamResult at http://struts.apache.org/2.x/docs/stream-result.html and the released code differ on how the name of the result stream is determined by the framework.  The documentation says that this name is defined by he 'inputName' parameter, while the released code uses the 'value' tag of the result annotation.
> In the following code, getXxx() is called to return the stream instead of getYyy() as the documentation would indicate.
> @Result (name="success", type=StreamResult.class, value="xxx", params={"inputName", "yyy", "contentType", "application/x-download", "contentDisposition", "attachment; filename=test.txt"})
> public class Download2Action extends ActionSupport
> {   
>     //param inputName says this should be called
>     public InputStream getYyy() throws Exception
>     { 
>     	return new FileInputStream("C:/temp/support.txt"); 
>     }
>     
>     // value tag actually determines that this is called instead
>     public InputStream getXxx() throws Exception 
>     { 
>     	return new FileInputStream("C:/temp/support.txt"); 
>     }
>     public String execute() throws Exception
>     {
>         return SUCCESS;
