Note

• When the user loads the corresponding PDF file and clicks the "Visit Assure Dynamics for more solutions | www.assuredynamics.com" linked header, he will notice that the redirect is not happening.

Affected versions

• Nightly v91.0a1

Affected platforms

• all

Steps to reproduce

1. Launch browser.
2. Flip the pdfjs.enableXfa to true.
3. Load the attached PDF file.
4. Click on the linked header.

Expected result

• The corresponding link is being opened in a new tab.

Actual result

• No redirect is observed.

Regression range

• Not a recent regression, but an implementation flaw.

This is a dynamic PDF feature that we are not going to support soon.

Same behaviour has the link from the second attached PDF.

Links from inside this PDF form aren't redirecting (clicking them has no effect).

Most links from this PDF have no redirect when clicked (ex. Old Age Security Act).

A similar issue is seen on this document with several links:

• link "209.2" on page 1, section 2.

• mail links "IRCC.CMBIMPInvestigations-EnquetesPMIDGRC.IRCC@cic.gc.ca", page 2

• link "infosource" in the footer.

• Weirdly enough, the "Personal Information Bank" link from the footer works correctly.

So this pdf (3e263476-df05-4803-bd04-9f9d0e058012.pdf ) is a bit painful:

• about "209.2" the JS behind is:

if (xfa.host.name == "Acrobat") {
 app.launchURL("http://laws-lois.justice.gc.ca/eng/regulations/SOR-2002-227/section-209.2.html", true);
}
else {
 xfa.host.gotoURL("http://laws-lois.justice.gc.ca/eng/regulations/SOR-2002-227/section-209.2.html");
}

• about the IRCC... is an underlined text in blue.
• about the "infosource", same problem as "209.2"
• and finally about "Personal...", it's a real <a href... link.

In the first case it's a bit hard to guess what's the url to use (it's possible of course but...).

About 0f5a3305-976f-4749-9ff4-41dd9720682b.pdf, the pattern is a bit different (app.launchURL(....) and we already used a workaround for such case in pdf.js:

The latest update fixed some of the PDFs in this bug, but not all.
