Jeromy Evans resolved WW-2711.
------------------------------

    Resolution: Not A Problem
      Assignee: Jeromy Evans

The StreamResult already includes a contentDisposition param that is evaluated.

eg. 
<result name="stream" type="stream">  
            <param name="contentType">${contentType}</param>
            <param name="inputName">inputStream</param>
            <param name="contentDisposition">attachment; filename="${fileName}"</param>
            <param name="contentLength">${contentLength}</param>
            <param name="bufferSize">1024</param>
        </result>
where contentType, fileName, contentLength and inputStream are properties of the action.

> I am using struts 2.0.11.1 and I just realized that I can not set contentDisposition dynamically. I ended up exteding the StreamResult type to allow this functionality. It would be worthwile if the StreamResult code is modified to allow this. It will only be a few lines of code. Bellow is my extension:
> public class DynamicStreamResult extends StreamResult {
> 	@Override
> 	protected void doExecute(String finalLocation, ActionInvocation invocation)
> 			throws Exception {
> 		String filename = (String) invocation.getStack().findValue(
> 				conditionalParse("name", invocation));
> 		contentDisposition = "filename=\"" + filename + "\"";
> 		super.doExecute(finalLocation, invocation);
> 	}
> }
