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.
> Support for setting contentDisposition dynamically for stream result type

> Project: Struts 2
> Issue Type: Improvement
> Affects Versions: 2.0.11.1, 2.0.11.2, 2.1.0, 2.1.1, 2.1.2
> Reporter: S. Farshi
> Assignee: Jeromy Evans
> Priority: Minor

> 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);
> }
> }
