Turning on quick transitions doesn’t change the behavior when I click the link. When I type the url directly into the location bar, I get the same error.
I tried switching back to the simplest implementation:
<a href="/my_app/my_pdf.pdf" canvas="false">...image tag here...</a>
With this implementation, when I type the url into the location bar, I get the file just fine (it lives in the public directory), but clicking the link in the app gives me a 404 error, slightly different when I have quick transitions turned on and off.
With quick transitions on:
Received HTTP error code 404 while loading <a href="http://my_app.heroku.com/my_pdf.pdf?quickling[version]=221228%3B0&__a=4">http://my_app.heroku.com/my_pdf.pdf?quickling[version]=221228%3B0&__a=4</a>
With quick transitions off:
Received HTTP error code 404 while loading <a href="http://my_app.heroku.com/my_pdf.pdf">http://my_app.heroku.com/my_pdf.pdf</a>
The “this is your FBML” block on the 404 page contains the standard Rails 404 page html, which FB overrides with its own content for display to the user.
Looking at the html for the link itself (with quick transitions turned off), FB has added an onclick event to it:
onclick="(new Image()).src = '/ajax/ct.php?app_id=123456789012&action_type=3&post_form_id=bdba90b597aaec1c2c1d6fc7716f5056&position=3&' + Math.random();return true;" (app_id obfuscated)
Is there a way to prevent that onclick from being attached?
