Check the Wiki page I gave you.
It uses target.appendJavaScript(location.href='+ url + ';);

Thanks Martin,

I guess what I am more curious in, is how come when I call the
downloadLink.onClick(), or do:


public void onPostProcessTarget(AjaxRequestTarget target)
{
   final File file = excelFile;
   IResourceStream resourceStream = new FileResourceStream(
new 
org.apache.wicket.util.file.File(file));

   ResourceStreamRequestHandler handler = new
ResourceStreamRequestHandler(resourceStream,  file.getName());
   handler.setContentDisposition(ContentDisposition.ATTACHMENT);

  
getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(handler);


I get the ajax error as shown above thread. It's only on onClick() call, or
when 
getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(handler);
is called..

Hi,

You should not write the binary response in the Ajax response.
The ajax response should return a redirect that will point to a url where
the binary data will be written back.

calling downloadLink.onClick() directly

2014-03-25 Thread eaglei22 
Hello, I currently am using a downloadLink to export a csv file to the user.
What I am currently doing is using a worker thread to handle the creation of
the csv file while an AjaxSelfUpdatingTimerBehavior updates the GUI of its
progress.. Then at completion the intent is to call downloadLink.onClick()
to invoke the behind the scenes work and get the user the dialog box
automatically to download the file.  I get everything running fine until
downloadLink.onClick() is called I get an ajax error: 

Wicket.Ajax.Call.failure: Error while parsing response: Error: Invalid XML:
��ࡱ�;��...`��Page 1�����=Bems_ID
First_NameMiddle_NameLast_NameUser_Status

it looks like the csv file is being outputted to the ajax debugger. 

What is the best way to invoke the onClick method automatically of the
DownloadLink class? 

Here is a snippet of what I am doing:

private void setupDownloadLink()
{
   IModel excelFileModel = new AbstractReadOnlyModel()
   {
  public Object getObject() 
  { 
 if(excelFile == null)
 {
 excelFile = new File(Error getting File);
 }
return excelFile;
  }
   };
  
 auditDownloadlink = new DownloadLink(auditDownloadlink,
excelFileModel)
 {  
public void onClick()
{
downLoadLinkClicked = true;
if (newSearchWasInitialized)
{
newSearchWasInitialized = false;
if (!extractionIsRunning)
{
worker = new 
CreateExcelExtractionWorker();
thread = new Thread(worker);
thread.start();
extractionIsRunning = true;
excelFile = null;
return;
}
}
  
if(!newSearchWasInitialized)
{
if (!extractionIsRunning)
{
  super.onClick();
}
}
}
 };
 
 auditDownloadlink.add(new Label(excelLabel, Excel));
 auditDownloadlink.setOutputMarkupPlaceholderTag(true);
 auditDownloadlink.setDeleteAfterDownload(true);
 auditDownloadlink.setCacheDuration(Duration.ONE_SECOND);
 auditDownloadlink.setVisible(false);
 
 
  findUserForm.add(auditDownloadlink);
}

Here basically when the user selects the button, it starts the worker
thread.. Then when completed, the AjaxSelfUpdatingTimerBehavior will call
the onClick() method, where in turn after each check is made then
super.onClick() is called to process the downloading of the file as normal:

public void onPostProcessTarget(AjaxRequestTarget 
target)
{
System.out.println(isRunning);
if(!extractionIsRunning)
{
if(downLoadLinkClicked)
{
  System.out.println(refreshed); 
  progressModel.setObject(Extraction 
to Excel file complete. Click
Download);
  auditDownloadlink.addOrReplace(new 
Label(excelLabel, Download));
  target.add(findUserForm);
  target.add(progress);
  stop(target);
  System.out.println(isStopped);
  downLoadLinkClicked = false;
  
  auditDownloadlink.onClick();
}
}
}
};
progress.add(progressUpdateBehavior);
progress.setOutputMarkupId(true);

Do I have to attach it back to the requestCycle?
