There is also the bug in MSIE that if there is a malformed tag like <a
href="whoops> it can cause the whole page be fetched twice my MSIE,
and sometimes the same thing happens with Firefox.
Unlikely this is your problem, but just a thought.

Are you downloading it with IE? IIRC, IE makes two requests for
anything it needs a plugin for or displays in an external application.

Thank Chuck for your time...
It seems to happen only when the PDF is being sent as a download as
part of appendToResponse... Even in the Apple Example for File
Downloads there is a repeat so I modified what I was doing and just
created the PDF, wrote it to the file system and then offered a link
to the file for download.
Again thanks for your input.

Thanks Chuck
Is that a default action that WO does - syncronize bindings... ?
Yes.
Causing multiple times... If I remove the appendToResponse PDF
download code it only shows a single call?
The easiest thing to do is to add a log message like this:
NSLog.out.appendln(new RuntimeException("Code Called from here"));
to your method so you can get a stack trace of the code that is
calling it.

Do these components synchronize their bindings? If you have a
hyperlink with
action = downloadPDF;
The downloadPDF() will get called multiple times by binding
synchronization.

Hi All
I have a component actton method that is calling a second
component
(not nested) and the result is the action method being called
twice
in the first component and also appendToResponse twice....
*******************************************************************
**
***
*************
public AttractionVoucher downloadPDF()
{
System.out.println("GOING TO START " );
AttractionVoucher nextPage = (AttractionVoucher)
pageWithName
("AttractionVoucher");
return nextPage;
}
*******************************************************************
**
***
******************************
If the next page, AttractionVoucher, I am overriding
appendToResponse with this:
*******************************************************************
**
***
******************************
public void appendToResponse(WOResponse r, WOContext c){
r.disableClientCaching();
r.removeHeadersForKey("Cache-Control");
r.removeHeadersForKey("pragma");
r.setHeader(mimeType, "content-type");
if (fileName != null) {
r.setHeader("inline;attachment;filename=\"" + fileName +
"\"",
"content-disposition");
}
try{
NSData fileToDownload = new NSData(new File
(pdfpathfordownload));
r.setHeader(Integer.toString(fileToDownload.length()),
"content-length");
r.setContent(fileToDownload);
}catch (Exception e) {
e.printStackTrace();
}
System.out.println("These are the headers " + r.headers());
}
*******************************************************************
**
***
******************************
Although the PDF is appearing it seems to call downloadPDF twice?
Has anyone an explanation or link to find out why this is
happening....
This is Tiger 5.3 WO and safari...
