-------------------------------------
Summary: Printing of PDF's does not work in Firefox
Key: WICKET-6986
URL: https://issues.apache.org/jira/browse/WICKET-6986
Project: Wicket
Issue Type: Bug
Components: wicket-core
Affects Versions: 9.10.0
Environment: Windows 10/Alma Linux
Reporter: Tilman Müller
Attachments: myproject.zip
Since we are migrated from wicket 8.12.0 to wicket 9.9.0 we running into a
problems with printing PDF's in FireFox. We developed a small (PDFViewer) class
above the WebMarkupContainer to view AND finaly print the PDF. Until wicket 8
this worked/works still fine in Firefox. However we now migrated to wicket
9.9.0 and viewing the PDF stil working in Firefox, but if you try to push the
printing button within the default pdfviewer in Firefox nothing happend (except
a (new) crash in the browser console). If you use the right mouse click menu
and using "This Frame" -> "Print Frame". I added a quickstarter project and
with 1 extra class "PDFViewer", Test.pdf with only the word "Test" in it and a
smal change in the default HomePage.html markup voor de PDF viewer. With this
simple project you can easaly reproduce this behaviour. So I wondering if
a) this is a bug sinds wicket 9 or
b) the fault can be found in the PDFViewer class (also look at the override of
the renderPage method - without this override we run into another strange
crash).
With kind regards.
