["Oscar Reitsma (JIRA)" <de...@myfaces.apache.org>]

Downloading file and closing dialog
-----------------------------------

                 Key: TRINIDAD-813
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-813
             Project: MyFaces Trinidad
          Issue Type: Bug
          Components: Components
    Affects Versions: 1.0.3-core
         Environment: Windows XP, MyFaces 1.1.5, Jetty 6.1.5, Trinidad 1.0.3, JDK 1.5
            Reporter: Oscar Reitsma
            Priority: Minor


The required functionality is as follows:
- In a dialog, the user selects parameters report to be generated.
- The user clicks OK, and the report is generated, and a file download is initiated
- the dialog is closed

When using the below implementation, the following exception is thrown, when a call is made to:
		RequestContext.getCurrentInstance().returnFromDialog(null, null);

Caused by: java.lang.IllegalStateException: STREAM
	at org.mortbay.jetty.Response.getWriter(Response.java:583)
	at javax.servlet.ServletResponseWrapper.getWriter(ServletResponseWrapper.java:122)
	at org.apache.myfaces.trinidadinternal.renderkit.core.CoreRenderKit._getHtmlWriter(CoreRenderKit.java:744)
	at org.apache.myfaces.trinidadinternal.renderkit.core.CoreRenderKit.returnFromDialog(CoreRenderKit.java:282)
	at org.apache.myfaces.trinidadinternal.context.DialogServiceImpl.returnFromDialog(DialogServiceImpl.java:173)
	at org.apache.myfaces.trinidadinternal.context.RequestContextImpl.returnFromDialog(RequestContextImpl.java:122)

implementation:
in the jspx of the dialog:
					<tr:commandButton text="OK" action="#{reportSelection.actionProcessReports}" partialSubmit="false" >
						<tr:fileDownloadActionListener method="#{reportSelection.downloadFile}"
							contentType="#{reportSelection.contentType}" filename="#{reportSelection.reportFilename}"/>
					</tr:commandButton>
The bean:
	public void downloadFile(FacesContext context, OutputStream out) throws IOException {
		// Here the report is generated, and written to the given OutputStream
                 downloadReport(selectedReport, out);
	        out.flush();
	} 
	public String actionProcessReports() { 
		RequestContext.getCurrentInstance().returnFromDialog(null, null);
		return "downloadComplete"; 
	}

Using the above implementation the download of the report completes as expected, but the dialog is not closed.
