FileUpload broken in Firefox 3.0.5
Hi all,
Just testing an application I have written which works perfectly fine
in Safari 3.2.1, but in Firefox 3.0.5 the FileUpload is failing.
Some code:
in form:
//upload form component
FileUploadField uploadField = new FileUploadField(picture);
form.add(uploadField);
in onSubmit() of form:
//get file that was uploaded
FileUpload upload = uploadField.getFileUpload();
if (upload == null) {
log.error(upload was null.);
return;
} else if (upload.getSize() == 0) {
log.error(upload was empty.);
return;
} else if (!checkContentTypeForImage(upload.getContentType())) {
log.error(invalid file type uploaded);
return;
} else {
String mimeType = upload.getContentType();
String fileName = upload.getClientFileName();
//get bytes, etc
byte[] imageBytes = upload.getBytes();
}
in Safari 3.2.1 the upload works fine
in Camino 1.6.6 the upload works fine also
in Firefox 3.0.5, the upload is null.
This bit of code hasn't changed for quite some time and last time I
tested it it was working fine. Latest Firefox update seems to have
killed it.
cheers,
Steve

I can confirm that the same code works on Firefox 3.0.4 - I just ran
it up on the older version. So its definitely the 3.0.5 update which
has the issue.
Any ideas?

Re: Multiple Copies of One Wicket App
I know this would be very difficult to create by hand, but if you automatically create a web.xml which includes 200 such filter definitions (replacing Application1 and dbfile1 with other values) I think that would do what you want. Note that here you obtain the db configuration file name as a filter init parameter, you should modify your application's init method accordingly.. filter filter-nameApplication1/filter-name filter-classorg.apache.wicket.protocol.http.WicketFilter/filter-class init-param param-nameapplicationClassName/param-name param-valuecom.mycompany.MyApplication/param-value /init-param init-param param-namedbFileName/param-name param-valuedbfile1.properties/param-value /init-param /filter filter-mapping filter-nameApplication1/filter-name url-pattern/dbfile1/*/url-pattern dispatcherREQUEST/dispatcher dispatcherINCLUDE/dispatcher /filter-mapping Sean W wrote: path: /ContextPath/wicket/BookmarkablePage It appears to me that using Wicket you cannot place anything in the path between the context path and the mounted name except for wicket, which is defined as your url-pattern.

Preserving mount point in URLs
Hi Wicketeers, My client has a web security infrastructure in place where a transparent proxy sits in front of the application server and filters requests based on URL pattern. I am trying to fit their first Wicket-based application into this infrastructure. We would like to allow requests based on URL pattern and authentication level and block all unrecognized requests. I'm using HybridUrlCodingStrategy to try and preserve the mount point in subsequent links and form URLs. This works well in some cases, but falls down when I pass parameters to a page. For example, a page mounted on mypage with no parameters results in a URL like this... http://host/myapp/mypage ...and links on the page are rendered like this... ?:wicket:interface:... ...which the browser recognizes as something like this... http://host/myapp/mypage.4?:wicket:interface:... ...which is great, since we can still implement our security policy based on the mypage portion of the URL. The problem is, if I pass a parameter to the page, the URL looks like this... http://host/myapp/mypage/key/value/ ...and links on the page look like this... ../../../?:wicket:interface:... ...which the browser reduces to this... http://host/myapp/?:wicket:interface:... This is no longer good, because we've lost the mount point. The problem appears to be the trailing slash added by AbstractRequestTargetUrlCodingStrategy.appendValue, which triggers an extra ../ to be added to the link URL. And if the mount point as a slash inside it, e.g. foo/bar, then neither case works properly. It's starting to feel that it will be difficult to preserve the mount point across requests. I know this has been discussed before on this list, usually in the context of pretty URLs, but I haven't seen a good solution. Has anyone been able to get something like this to work well? jk - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
ModalWindow width as %
Hi there,
In ModalWindow as defined in wicket-extension the width has a fixed
length expressed in pixel (600px). I would like to have the width in %
but the widthUnit is available only when the the component is not
resizable.
In fact in ModalWindow.getWindowOpenJavascript() there is the following:
..
if (isResizable() == false)
{
buffer.append(settings.widthUnit=\ + getWidthUnit() + \;\n);
buffer.append(settings.heightUnit=\ + getHeightUnit() + \;\n);
}
...
How could i setting the width as % and mantain the resizability of the
component ?
And why this behaviour is present ?
Thanks,
Emanuele

Re: ModalWindow width as %
If I'm correct, the modal window uses js to determine the resizing in px.
If you want it to resize in % of screen, you'd probably have to override
modal.js to determine the appropriate % to set the window width.
However, if you want the window to be some percentage wide, you don't really
want it resizeable, you want it to be some percentage wide. If you want the
window to start at 50% width and then be resizeable after the fact, you
could just detect the client screen width and set the modal window width to
half of that to start.
Regards,
Matt.

Dynamic PDF Creation
I am using FOP to create a PDF dynamically based on user input into a web
form. I don't have a problem creating the PDF only with the display of it.
I need that PDF to be immediately sent to the user via a redirect or
download. so something like this
@Override
public void onClick(){
validateUserDataFromForm();
if(!hasErrorMessage()){
ByteArrayOutputStream pdfData =
factory.createPDF(startDateThatIsSetViaTheForm, endDateThatIsSetViaTheForm,
reportType);
// Output the steam to a page I can redirect to.
// I can use a File if ByteArrayOutputStream is making things tough.
// I am fine if the user gets prompted like a download link, but I want
a single click to create and prompt for download.
}
}
Here is what I have tried.
1) Making the PDF a resource: This worked initially as I needed it to, but
I was having problems with the resource being reused and while the report
needed to vary on each generation. Basically, I need to create the PDF,
give it to the user, and then destroy the copy on the server. Every time
the user clicks the create button a new PDF needs to be built and sent to
the user. I also don't like this option as I don't want to waste memory by
adding too many resources that are not re-used. I need the user data to
update the display of the PDF when it is built, so I need the link to pass
in new values to the createPDF function every time.
2) Something like this...
final Response response = getRequestCycle().getResponse();
response.setContentType(application/pdf);
response.setContentLength(pdfout.size());
try{
OutputStream stream = response.getOutputStream();
stream.write(pdfData.toByteArray());
stream.flush();
}catch(Exception ex){
throw new RuntimeException(ex);
}
That results in an error like so...
[org.apache.wicket.protocol.http.WicketFilter] - closing the buffer error...
Any help would be appreciated! Thanks!

Have a look at RequestCycle#setRequestTarget.
Additionnaly, you may have a look at SubmitLink, since the validation
step has nothing to do in the onClick of a link

Here is what I have tried.
1) Making the PDF a resource: This worked initially as I needed it to,

I was having problems with the resource being reused and while the report
needed to vary on each generation. Basically, I need to create the PDF,
give it to the user, and then destroy the copy on the server. Every time
the user clicks the create button a new PDF needs to be built and sent to
the user. I also don't like this option as I don't want to waste memory
by
adding too many resources that are not re-used. I need the user data to
update the display of the PDF when it is built, so I need the link to
pass
in new values to the createPDF function every time.
2) Something like this...
final Response response = getRequestCycle().getResponse();
response.setContentType(application/pdf);
response.setContentLength(pdfout.size());
try{
OutputStream stream = response.getOutputStream();
stream.write(pdfData.toByteArray());
stream.flush();
}catch(Exception ex){
throw new RuntimeException(ex);
}
That results in an error like so...

error...
Any help would be appreciated! Thanks!

generalized way to ignore mouse input during screen refresh?
So one problem we've seen in a few places occurs when a (somewhat slow) request happens that refreshes the page or component, but then the user clicks on a link on the pre-refresh screen, and ends up getting a nasty exception thrown, since the component clicked on no longer exists Is there a single, easy workaround for this? Obviously you can try to limit the situations where this occurs, like my redrawing as little as possible, or otherwise making things less time consuming, but it still seems like it would be good if there was a general mechanism for ignoring inputs once some kind of Ajaxy-process is started... - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Dynamic PDF Creation
Some little points:
- on the onsubmit of a form (or any onsubmit like in button,
submitlink, ajaxfallbackbutton, etc.) you don't need to verify the
validity: wicket does it for you, it firsts validate the form and then
call onsubmit if there is no error. Thus it means you can remove your
validateCriteria and if(!haserrormessage)
- you don't need to implement the whole IRequestTarget interface
yourself, instead you may use some existant implementation (this
requires less work for you) for exemple ResourceStreamRequestTarget
(which is the most usefull in your case). There are dozens
implementation of IRequestTarget in the framework, just have a look to
find one which fit your needs.
- this is often dangerous/expensive to add non-static inner classes
(like you do with your anonymous implementation), because of
serialisation of pages (reference to your top level class is hold in the
inner class, and thus gets serialized if the inner instance needs to).
Be aware of your session size, it is really important under heavy load.

Re: generalized way to ignore mouse input during screen refresh?
I created a reusable component, PanelWithAjaxBusyIndicatingMask, which extends Panel. The functions it has: It will add a transparent mask layer to the current page to prevent further UI interactivity when there are any busy Ajax activities. The mask layer will have an animation gif and a configurable display text (the default is: Please wait…). Both the display text and the animation gif file are configurable in the constructors. I am proposing it to the Wicket developers. Hope they will incorporate it into the next release.

Re: How / where can I contribute my source code to the wicket?
You're very welcome to start a Wicket Stuff project (wicketstuff.org) or contribute it to one that already exists, depending on where it would fit, perhaps one noted below [1]. If you believe it is something that belongs in core, you should open a JIRA [2]. Prepare yourself - it's not likely to be accepted. Depending on the type of component, it'd probably go into wicket-extensions. The core developers don't add a lot of rich components to core because of the obvious maintenance issues of maintaining someone else's code. Instead, they focus on giving an extremely powerful, easy to extend framework that has all of the primary components needed that just work (tm).

Re: FileUpload in a Panel
Yes - a FileUpload can be in any component (though it will need to be nested
in some parent multi-part form). Your error below has nothing to do with it
being in a panel. In later versions of 1.4, there was a change that
requires a FileUpload component to have a model to store it's data. You
need to call the constructor like new FileUpload(ID, new Model())
