Yes it would be usefull. But where does DocumentResourceListener came from? I'm using wicket 1.3.6 and DocumentResourceListener is not available.

Just place all the following files at the same package and you will get a working example (I tested them with FF35 and IE7). import org.apache.wicket.ajax.AjaxRequestTarget; import org.apache.wicket.ajax.markup.html.AjaxLink; import org.apache.wicket.markup.html.WebPage; import org.apache.wicket.markup.html.basic.Label; import org.apache.wicket.model.AbstractReadOnlyModel; /** * @author Ernesto Reinaldo Barreiro (reier...@gmail.com) * */ public class TestPage extends WebPage{ private Label text; private String labelText = "Hi!"; private DocumentResourceListener documentResourceListener; /** * */ public TestPage() { AjaxLink<Void> link = new AjaxLink<Void>("link") { private static final long serialVersionUID = 1L; @Override public void onClick(AjaxRequestTarget target) { TestPage.this.labelText = "Hi! and donwload image!"; if(target!= null) { target.addComponent(TestPage.this.text); String url = documentResourceListener.getURL().toString(); target.appendJavascript(";alert('Hi');window.location.href='"+url+"';"); } } }; add(link); text = new Label("text", new AbstractReadOnlyModel<String>() { private static final long serialVersionUID = 1L; @Override public String getObject() { return TestPage.this.labelText; } }); text.setOutputMarkupId(true); add(text); documentResourceListener = new DocumentResourceListener("listener", new MyPdfResource()); add(documentResourceListener); } } --------------------------- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> <html xmlns:wicket="org.apache.wicket"> <head> </head> <body> <a wicket:id="link">Click Me</a> <span wicket:id="text"></span> <div wicket:id="listener"></div> </body> </html> --------------------------------- import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import org.apache.wicket.markup.html.DynamicWebResource; import org.apache.wicket.protocol.http.WebResponse; /** * @author Ernesto Reinaldo Barreiro (reier...@gmail.com) * */ public class MyPdfResource extends DynamicWebResource { private static final long serialVersionUID = 1L; static int BUFFER_SIZE = 10*1024; /** * */ public MyPdfResource() { } /* (non-Javadoc) * @see org.apache.wicket.markup.html.DynamicWebResource#getResourceState() */ @Override protected ResourceState getResourceState() { return new ResourceState() { @Override public String getContentType() { return "application/pdf"; } @Override public byte[] getData() { try { return bytes(MyPdfResource.class.getResourceAsStream("jta-1_1-spec.pdf")); } catch (Exception e) { return null; } } }; } public static byte[] bytes(InputStream is) throws IOException { ByteArrayOutputStream out = new ByteArrayOutputStream(); copy(is, out); return out.toByteArray(); } @Override protected void setHeaders(WebResponse response) { super.setHeaders(response); response.setAttachmentHeader("jta-1_1-spec.pdf"); } public static void copy(InputStream is, OutputStream os) throws IOException { byte[] buf = new byte[BUFFER_SIZE]; while (true) { int tam = is.read(buf); if (tam == -1) { return; } os.write(buf, 0, tam); } } } Just replace "jta-1_1-spec.pdf" with your own PDF file on MyPdfResource and the exampel should work. An important bit here if @Override protected void setHeaders(WebResponse response) { .... response.setAttachmentHeader("jta-1_1-spec.pdf"); } which makes the file to treated as an attachment instead of replacing the current page. Best, Ernesto P.S. Would it useful to add this to Wicket's wiki? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
