External viewer does not open

[sfrankhtwk]

With JabRef 3.0 on Windows 8.1, using jre1.8.0_66, and when the external pdf viewer is defined by MIME type, clicking the pdf symbol in the table view does not open the viewer for older pdf files in the database. Status line says "external viewer called". When setting the external application to the actual viewer (Acrobat), opening pdf on click works for all files.

Do you get any exceptions? (See Help -> Show error console -> Exceptions)

When you say "older", are those in the pdf-field or in the file-field?

@sfrankhtwk Any news regarding the questions from @oscargus ?

[sfrankhtwk]

Dear Oscar,

sorry for the late reply, I could check that only after returning to my office.

•    There are no exceptions in the error log
  

•    The files are in the file field
  

Thanks for your help and kind regards

@sfrankhtwk Could you provide an explicit example how we can reproduce this issue.
bib file, screenshots, explicit steps or anything the likes?

[stefan-kolb]

@JabRef/developers I read something about older PDF files in the first post. Could this be related to the old PDF/PS fields?

[sfrankhtwk]

Dear Mr. Kolb,

of course I can, please apologize my late answer.

When external file type PDF is set to application/pdf (see enclosed file not_working_settings.jpg), the following occurs:

• Clicking on pdf symbol (red square) of an older database entry (time stamp 2014-…): status reads „external viewer called“ (Externer Betrachter aufgerufen), but pdf does not open; e.g. #14: Beese 2014 (see file pdf_does_not_open.jpg)
• Clicking on pdf symbol of a more recent entry (time stamp 2016-…): same status, pdf opens; e.g. #1 IFLA Working Group … 2009 (see file pdf_opens.jpg)
  When external file type PDF is set to the path of the pdf viewer (see file working_settings.jpg), the pdf opens in both cases, and the status ist he same

The database entries for the examples are:

@Article{114,
  Title                    = {Mit LENA zur Facharbeit : UB Chemnitz stellt Schülern virtuelle Lotsin zur Seite},
  Author                   = {Beese, Michael},
  Journal                  = {BIS : das Magazin der Bibliotheken in Sachsen},
  Year                     = {2012},
  Number                   = {2},
  Pages                    = {114-115},
  Volume                   = {5},
  File                     = {:Auskunft\\bis_5.2012.114.pdf:PDF},
  Keywords                 = {IJ. Reference work; CD. User training - promotion - activities - education; Informationsdienst; Informationskompetenz;Benutzerausbildung; E-Learning},
  Owner                    = {sfrank1},
  Review                   = {…},
  Timestamp                = {2014.08.14},
  URL                      = {http://nbn-resolving.de/urn:nbn:de:bsz:14-qucosa-89425}
}
@Book{GBV-604815212,
 Title                    = {National bibliographies in the digital age : guidance and new directions},
  Author                   = {{IFLA Working Group on Guidelines for National Bibliographies}},
  Editor                   = {\v{Z}umer, Maja},
  Publisher                = {Saur},
  Year                     = {2009},
  Address                  = {München},
  Series                   = {IFLA series on bibliographic control},
  Volume                   = {39},
  File                     = {:Literatur_NB\\nationalbibliographiesdigitalage\\9783598441844.fm.pdf:PDF},
  Owner                    = {sfrank1},
  Timestamp                = {2016-02-08}
}

Hence, the pdf is in the same field, in the same format.

I hope this helps.

Many thanks for your help.

Kind regards

Stefan

Hi Stefan,
I'm currently investigating your reported issue but cannot reproduce it here.

As you answered directly via mail to to the notification of @stefan-kolb your attached screenshots are not visible for us at GitHub (here: #556)

Could you please upload the screenshots there?

What I currently understand (without seeing the screenshots) is, that the default viewer is not called correctly, but you have to provide an explicit path to the viewer to be called?

[sfrankhtwk]

Dear Matthias,

here are the screenshots.

I hope they will help you, but perhaps not -- your summary describes the problem perfectly well. Perhaps I should stress that this only occurs for data sets added before a certain (and not exactly known) time stamp. For more recent additions, everything works fine.

Thanks

Stefan

Settings with explicit path to viewer work for all data sets:

Settings without explicit path to viewer do not work for older data sets:

Status after failed call of pdf viewer:

Status after successful call of pdf viewer (pretty much the same):

Could you please also provide the bibtex code of an entry for which the pdf viewer was called successfully and for one entry where it was not successful (so one of the older ones). Thanks! (I suspect you closed this issue by accident.)
