Re: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13
Just a small observation that might help. Move code from PdfViewer contructor to onInitialize. This makes URL generation safer although it doesn't explain why your code worked until 6.12.0. I guess it depends on the mount path of your page. Most probably it is /wicket/bookmarkable/...

Hi,
I've created a quickstart based on your code but I can't reproduce the
issue. I've shared it on Dropbox:
https://www.dropbox.com/s/qmolvzvp9a0xplf/ResourceIssue.tar.gz?dl=0
The only thing I've noted is that your resource url doesn't have starting
segment 'wicket', i.e my resource url is:
./wicket/resource/org.apache.wicket.Application/pdfProducer
Maybe you have some custom setting for wicket segments ('wicket',
'bookmark', etc...)?
The problem (which I think is a bug) is in the way the url is produced.
The line
String url = (String)RequestCycle.get().urlFor(resourceReference,
null);
Produces the url to use for the resource ref.
In the non-working version it returns:
../resource/org.apache.wicket.Application/pdfProducer
If I set a breakpoint just after this line and I manually remove the
first dot in the string using the debugger to get:
./resource/org.apache.wicket.Application/pdfProducer
and then let the code continue to run, my pdf appears correctly.
The debug trace also shows the correct uri.

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13
Martin,
I'm looking into mounting the resource but there is something that I don't
understand.
Currently I am creating the resource in my panel and passing the pdf I want to
display into the constructor of the resource. If I mount the resource, how do I
provide it with the dynamically generated pdf? I don't even see a way of
getting a hold of the resourceReference object created and mounted in the
WebApplication init() method. Perhaps I need to also register it as an
application-shared resource, then access it in my panel constructor and add the
pdf there?

Hi,
I think I see what happens.
The ResRef is created as a local variable to create the url and then discarded.
Wicket has something called ResourceReferenceRegistry. When a ResRef is used to
create an url to it it is automatically registered in the registry.
It seems after 6.13 there is no such auto-registration for your ResRef for some
reason.
You should have some WARNs in the logs.
I see nothing component specific in your ResRef so I'd #mountResource() it.
This way it will be always available.

By setting a breakpoint in Eclipse I have determined that code in the

get the problem.

Martin,
I'm looking into mounting the resource but there is something that I don't
understand.
Currently I am creating the resource in my panel and passing the pdf I
want to display into the constructor of the resource. If I mount the
resource, how do I provide it with the dynamically generated pdf? I don't
even see a way of getting a hold of the resourceReference object created
and mounted in the WebApplication init() method. Perhaps I need to also
register it as an application-shared resource, then access it in my panel
constructor and add the pdf there?

Hi,
I think I see what happens.
The ResRef is created as a local variable to create the url and then
discarded.
Wicket has something called ResourceReferenceRegistry. When a ResRef is
used to create an url to it it is automatically registered in the registry.
It seems after 6.13 there is no such auto-registration for your ResRef for
some reason.
You should have some WARNs in the logs.
I see nothing component specific in your ResRef so I'd #mountResource() it.
This way it will be always available.

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13
The problem (which I think is a bug) is in the way the url is produced. The line String url = (String)RequestCycle.get().urlFor(resourceReference, null); Produces the url to use for the resource ref. In the non-working version it returns: ../resource/org.apache.wicket.Application/pdfProducer If I set a breakpoint just after this line and I manually remove the first dot in the string using the debugger to get: ./resource/org.apache.wicket.Application/pdfProducer and then let the code continue to run, my pdf appears correctly. The debug trace also shows the correct uri. 2015-03-13 17:59:30,292 DEBUG - ServletWebRequest - Calculating context relative path from: context path '', filterPrefix '', uri '/wicket/resource/org.apache.wicket.Application/pdfProducer' 2015-03-13 17:59:30,298 DEBUG - ServletWebRequest - Calculating context relative path from: context path '', filterPrefix '', uri '/wicket/resource/org.apache.wicket.Application/pdfProducer' 2015-03-13 17:59:30,301 DEBUG - ServletWebRequest - Calculating context relative path from: context path '', filterPrefix '', uri '/wicket/resource/org.apache.wicket.Application/pdfProducer' 2015-03-13 17:59:30,305 DEBUG - CompoundRequestMapper - One compatible mapper found for URL 'wicket/resource/org.apache.wicket.Application/pdfProducer' - 'Mapper: org.apache.wicket.core.request.mapper.ResourceReferenceMapper; Score: 1' Maybe someone knows how to fix this?

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13
That's not really possible. The pdf is produced by itext from a template with
lots of parameter. It would require too large a change in the code and would
couple the pdfViewer panel too closely to the domain code.
If, as Martin suggests, the automatic registering of the resource is not being
done in the ResourceReferenceRegistry maybe there is something I could do to
register and then unregister the resource similar to the way it must have been
done in 6.12..

RE: PDF viewed in panel via ResourceReference works in 6.12 but not in 6.13
Thanks Martin an others. I am always impressed with the helpfulness of the people on this list. I will look into what you suggest. In the meantime I'm trying to find out more information about the differences between versions and I set the logger level to DEBUG and obtained the traces below from working and non-working versions. Maybe this will help shed some light on what is happening. I see some differences like uri for working version starts with /wicket/resource but non-working version starts with /resource/ but I don't know what the differences mean. Maybe someone know about this change? If the difference in the way resource reference registration works between 6.12 and 6.13 is an unintended change in behavior between versions, it seems like it should be fixed. If it is an intended change, then it should be documented.

Except #getSession(), but you can use Session.get() and cast it. It is the same. If you need the component to be able to generate the PDF bytes then you need to implement IResourceListener interface. In #onResourceRequested() you can generate the bytes and write them to the Response: getResponse().write(byte[]). The change you need to do is in #urlFor(): urlFor(ResourceListener.INTERFACE, parameters)) Martin Grigorov Freelancer, available for hire!

Passing something that allows you to produce the byte []?

Thanks Ernesto,
I don't know how to pass a byte[] as a parameter.

Pass the info as parameters on the request to the mounted resource?

Martin,
I'm looking into mounting the resource but there is something that I
don't understand.
Currently I am creating the resource in my panel and passing the pdf I
want to display into the constructor of the resource. If I mount the
resource, how do I provide it with the dynamically generated pdf? I
don't even see a way of getting a hold of the resourceReference object
created and mounted in the WebApplication init() method. Perhaps I
need to also register it as an application-shared resource, then
access it in my panel constructor and add the pdf there?

Hi,
I think I see what happens.
The ResRef is created as a local variable to create the url and then
discarded.
Wicket has something called ResourceReferenceRegistry. When a ResRef
is used to create an url to it it is automatically registered in the registry.
It seems after 6.13 there is no such auto-registration for your ResRef
for some reason.
You should have some WARNs in the logs.
I see nothing component specific in your ResRef so I'd #mountResource() it.
This way it will be always available.

By setting a breakpoint in Eclipse I have determined that code in
the resource that produces the response (newResourceResponse) is
never called in 6.13. After migrating to the latest version (6.19) I
still get the problem.
I've looked at the release notes for version 6.13 and see some
changes related to IResource but nothing that looks related to this problem.
I'm hoping someone has seen something similar. Here is some of the
