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:

> Result annotation for StreamResult uses value tag instead of inputName
> parameter for the name of the stream property

> Key: WW-2082
> URL: https://issues.apache.org/struts/browse/WW-2082
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - CodeBehind
> Affects Versions: 2.0.8, 2.0.9
> Environment: MS Windows, IBM RAD 7 Test Environment, WAS 6.1, Java 5
> Reporter: Kevin Dahlhausen
> Assignee: Don Brown
> Priority: Minor
> Fix For: 2.1.2
>
>
> 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;
> }
> }
