Oh... I did not realize that. Great reference, I'll see what I can
figure out, thanks!

File uploading doesn't work with AJAX without faking it using iframes
or using Flash. It doesn't matter if you're using Tapestry or not,
this is a limitation of AJAX itself. See this:

Hi,
I've been working on Image file upload and display. With the help of
a previous thread, I was able to get a fully working test component
that could have a client upload a file from a form, and then have the
file saved on the server and rendered back to the client in the browser.
I've moved on to integration of this concept into my actual
application. I'm having an issue capturing the UploadedFile in any
event handlers on a page where the form is within a Zone. The form is
also within a Block that is delegated in case that factors in at all.
When the form is submitted, the UploadedFile object is null, and thus
I cannot handle the object.
In my test component, the UploadedFile object resolves to a reference
to the Image file uploaded by the client (had they uploaded one and
no exception occurred). I did another sanity check by integrating the
upload component into another form for the same Entity in my
application that is not within a Zone or Block. The UploadedFile
object was valid in this page as well after form submit, leaving me
to think there is something about the Zone or Block that is
interfering with the results I expected.
This is how I have been using the Upload component
Page:
@Property
private UploadedFile uploadedFile;
public void onSuccess(){
if(uploadedFile == null){
log.debug("Image file was not provided");
}else{
imageManager.saveImage(uploadedFile);
}
}
TML:
<input t:type="upload" t:id="uploadedFile" />
Also since I'd had a couple threads recently where I had forgot to
use the t:zone attribute properly, I tried out t:zone on the upload
component to sanity check that as well, but that did not appear to
change anything.
Is anyone familiar with what challenge(s) I may be facing here in
getting the upload to work?
Thanks,
Rich
