Display "PDF Page" uses a path but the path is undefined.

Same Issue. Not able to use 'PDF page' dispaly

Need more info. Is there an error? One what page?

As mentioned earlier, there is no way to edit the 'PDF page' display because of the error in the views edit page.

I think this may be related to the problem I'm having. It used to work back in the spring, but now when I try to edit the settings for PDF Fields (PDF Page: Row style options) or "PDF Template Settings" (possibly others) when I try to click either Apply or Cancel, an AJAX error dialog pops up. The only way to get out of it is to close the dialog so I can't change any settings.

The CustomMessage in the very long error message is "The response failed verification so will not be processed" and I see the path it lists is "http://mydomain.com/admin/structure/views/ajax/display/exhibit_generator..." which is not a valid path. Both of those settings pages also have template related fields. I have the same problem even when trying to create a new view from scratch and add a PDF Page.

Drupal 7.39
Views: 7.x-3.11
Views PDF: 7.x-1.4 and 7.x-1.4+4-dev (2015-Mar-03)

Help me help you with a step by step how to replicate this. I'm not having this problem. I get warning that no path is defined, but it doesn't prevent anything and entering a path makes the warning go away.

For me, I can just create a new view, only adding a name and keeping the defaults, then click "Continue & Edit". Add "PDF Page". Click "Settings" for "PDF Fields | Settings" or "PDF Template Settings:No". Without changing anything, click "Apply" or "Cancel".

I get an error dialog box that says:

Maybe it's from upgrading previous versions of drupal/views or another module? I'm not a programmer so I can't decipher the error.

The issue is, when I try to add 'PDF page', the page goes white and there is now way to use that disply.

@troybthompson, I'm now also having this issue. It looks like it's related to changes in AJAX from Drupal Core 7.38 -> 7.39. However, this looks like a different issue. I'll start a bug report for that issue.

@beautifulmind, After you get the error, does it say anything in Reports > Recent log messages, relating to Views PDF? Is it a totally white WSOD, or is there anything on the screen?

@troybthompson, new issue is here:
#2563263: AJAX Error: The response failed verification so will not be processed.

@vegansupreme Thank you.

There is nothing in the log and when trying to add the 'PDF page', its all WSoD.

Regards.

I am having the same WSOD.

Is the only current solution to downgrade to 7.38?

Go Vegan! :-)

:-)
Downgrading core to 7.38 would probably fix the AJAX error. I'm not sure if it would fix the WSOD, as I'm unable to replicate it.

@beautifulmind Do you know if Views PDF was working for you before Aug 19th, when 7.39 was released? Would you be able to downgrade to 7.38 and report back results?
Downgrading might be a temporary work around until we get a proper fix.

I actually thought that the WSOD was a problem with Jquery but I fiddled around with the settings and the WSOD prevailed. I don't think there is any safe way of downgrading unless you have a backup from before you upgraded - unless there were no db updates.

This is the path where I see the WSOD: /admin/structure/views/view/pdf_comments/edit/pdf_1

Thanks for your time.

Hello,
Certainly, I will give it a try and post an update here.

Regards.

Can anyone having the WSOD problem try the patch here for Views? #2595607: Passing wrong URL to ajax.url It's for Views 7.x-3.x-dev.
Alternately, try the patch here #2563263: AJAX Error: The response failed verification so will not be processed. for Views PDF. Please try one or the other, but not both. My vote is for patching Views, but it's up to Views maintainers to commit it.

Hello,
Thanks for the suggestion.
If the views will not have that patch accommodated in next release, it would be of no use. Do you recommend the second patch over the first one?

Regards.

Both patches do pretty much the same thing, but the second one is smaller and fixes the problem in more places. It's more of an upstream fix. Try the Views patch, and if it doesn't help, the Views PDF one probably won't help either. The views patch should be applied to the dev version of views. If the patch fixes your problem, then comment on the issue in Views and we can push to get it RTBC.

I tried the Views Patch on the latest views-7.x-3.x-dev, and it did not work for me.

Thanks.
/GrN.dk

To get the picture. The problem falls with the Drupal 7.40 (39 start the problem) and Views ? or might be inside this module ?

Anyone having this problem please try the patch in this issue #2599690: Library URL has change
or manually downloading TCPDF and FPDI and placing them in the libraries folder naming them:
"tcpdf" and "fpdi"

That patch above is now committed to 7.x-1.x-dev.
Not sure if it will help, but I'm unable to duplicate, so it's hard for me to find a solution.

When I'm creating new view block Pdf page its showing blank page
when i'm back to view , For me its giving error
"Display PDF Page uses a path but the path is undefined"

Please Someone help into this??

I solved this issue by clicking on the '/' on the side of 'Path' , under PDF SETTINGS, and setting a new pathname.
Just like like a similar issue showed on this website: https://www.ostraining.com/blog/drupal/services/

I solved this issue by setting a new pathname , clicking on the '/', on the side of 'path' under PDF SETTINGS.

I tried the patch, but no help.
Issue still persist. I still get the WSOD when trying to add the PDF page.

PHP: 5.5
Drupal: 7.50

Regards.

sorry to poke this again, after 3 years but I'm having the same problem today. I'm trying to add a PDF Page and all I get is the WSOD.. I checked the php error log and found this:
[27-Aug-2019 14:27:14 Europe/Paris] PHP Fatal error: Class 'Com\Tecnick\Pdf\ClassObjects' not found in /.../sites/all/libraries/tcpdf/tcpdf.php on line 35

Could that be a hint towards solving this issue?

---
Edit: Solved my problem by reinstalling the libraries. The newest TCPDF from here: https://github.com/tecnickcom/TCPDF and an older Version of fpdi from here: FPDI-1.6.2 (because of this post: https://www.drupal.org/project/views_pdf/issues/2875164) That did the trick for me, yay!

I'm still having this issue! WSOD with latest Drupal 7 and latest libraries... Is there a solution?

Provide me an updated version of how can I can replicate this on a clean Drupal 7 setup.

with the latest version of everything (drupal, views, ctools, views-pdf dev, tcpdf fpdi) I didn't got a WSOD but a warning on Views UI of having path empty.

I'm gonna close thing one, please open a new one in case this issue still happen with latest version.
