Hi,

I created a button, when users press the button, the page will export some data to a file format and download, I write some codes for server onclick event, it works, but it still has redirect exception on server log.

code example:
-------------------------------------------------
page.getResponse().setContentType("application/octet-stream;");
page.getResponse().addHeader("Content-Disposition","attachment; filename=" + exportFileName + ";");
......
Writer w = page.getResponse().getWriter();
w.write( key_sb.toString() );
w.flush();
---------------------------------------------------
server error message:
2007/12/20 下午 01:36:55 org.apache.catalina.core.StandardWrapperValve invoke
Servlet.service() for servlet jsp threw exception
java.lang.IllegalStateException
at org.apache.catalina.connector.ResponseFacade.sendRedirect(ResponseFacade.java:435)
at com.codecharge.components.Page.redirect(Page.java:523)
......

Thanks


Vincent
