p:fileDownload Problem with several Pdf-Links

[mario_]

Hi,

I'm using PrimeFaces-2.2.1 on Mojarra-2.0.4.

Following Problem:

Defining a site with two links to download pdf files:

Code: Select all

	<h:form>
	<h:commandLink ajax="false">
		<h:outputText value="Pdf 1" />
		<p:fileDownload value="#{testBean.getPdf('Pdf 1')}" />		
	</h:commandLink>
	<h:commandLink ajax="false">
		<h:outputText value="Pdf 2" />
		<p:fileDownload value="#{testBean.getPdf('Pdf 2')}" />				
	</h:commandLink>
	</h:form>

And the method for the pdf:

Code: Select all

	public StreamedContent getPdf(String value) throws IOException, DocumentException {
		Document document = new Document(PageSize.A4);
		ByteArrayOutputStream out = new ByteArrayOutputStream();
		PdfWriter.getInstance(document, out);
		document.open();
		document.add(new Phrase(value));
		document.close();
		
		return new DefaultStreamedContent(new ByteArrayInputStream(out.toByteArray()), 
				"application/pdf", 
				"Doc-"+ value + ".pdf");
	}

When I click the first time on one of the links, every think is fine. But once you click the first link, the second link will show the same Pdf.

I think because the site is not refreshed and the hidden input field (for the parameters) is still in the site. So this will post too to the server.

The Problem comes with the Tag h:commandLink. Since the lastest version of Mojarra, the Prolbem is solved. But using p:commandLink instead of h:commandLink comes to the old problem:

Code: Select all

   <h:form>
   <p:commandLink ajax="false">
      <h:outputText value="Pdf 1" />
      <p:fileDownload value="#{testBean.getPdf('Pdf 1')}" />      
   </p:commandLink>
   <p:commandLink ajax="false">
      <h:outputText value="Pdf 2" />
      <p:fileDownload value="#{testBean.getPdf('Pdf 2')}" />            
   </p:commandLink>
   </h:form>

Code: Select all

public StreamedContent getPdf(String value) throws IOException, DocumentException {
      Document document = new Document(PageSize.A4);
      ByteArrayOutputStream out = new ByteArrayOutputStream();
      PdfWriter.getInstance(document, out);
      document.open();
      document.add(new Phrase(value));
      document.close();
      
      return new DefaultStreamedContent(new ByteArrayInputStream(out.toByteArray()),
            "application/pdf",
            "Doc-"+ value + ".pdf");
   }

Since I can use h:commandLink, bugfixing of p:commandLink isn't ugent any more
