Description
Since upgrade to CSS4J 0.20, it is no more possible to customize the pdf stylesheet with styles using URLs.
The issue happen because there no BaseURL associated to the exported document.
An easy way to work around this issue is to add a
<base href="$doc.externalURL" />
tag in #pdfhtmlheader.vm# after the title tag. This will fix a value for the BaseURL of the document, and this will avoid the NPE happening in the CSS4J library.
The error is silent and cause the CSS not to be applied.
Here is the stacktrace of this issue that could reach the logs:
