Error rendering macro ‘viewpdf’
The viewfile macro is unable to locate the attachment “test - 1.pdf” on this page

If we view the attachment after an import the url will be:
http://url/pages/worddav/preview.action?fileName=test+-+1.pdf&pageId=1234667

Whereas the Storage macro is:

<p><ac:structured-macro ac:name=“view-file” ac:schema-version=“1” ac:macro-id=“eaacb52e-73ec-467d-a333-f206f33d444b”><ac:parameter ac:name=“name”><ri:attachment ri:filename=“test &ndash; 1.pdf” /></ac:parameter><ac:parameter ac:name=“height”>250</ac:parameter></ac:structured-macro>&nbsp;<ac:structured-macro ac:name=“viewpdf” ac:schema-version=“1” ac:macro-id=“e9f2572d-9951-4148-9449-d934c343ee02"><ac:parameter ac:name=“name”><ri:attachment ri:filename=“test &ndash; 1.pdf” /></ac:parameter></ac:structured-macro></p>

Workaround

Update the Storage format and replace the ndash character with a dash

or

Edit the page and select the attachment again on the pdf macro.
