Hello, for starters, I read the README.txt from start to finish.. and have checked the issue queue in entirety as well
I'm getting the error FBML Error (line 29): illegal tag "body" under "fb:canvas"
I understood this to mean that fb_fbml theme is not being detected... but it actually is. I enabled it in the admin/build/themes section and it is showing up as a separate theme in the admin/build/blocks section
I forced it to be the default theme for testing purposes and then, everything starts works fine but it breaks up my original website (obviously), so its not a route I can take. I enabled fb_devel and that indicated just one error related to "&". I fixed it but I guess it is unrelated to the theme not getting detected
Any idea what else I need to do? Maybe I am missing something simple here...

Subscribe: FBML Error (line 46): illegal tag "body" under "fb:canvas"

Making the fb_fbml theme default did not alleviate the problem. I definitely don't have any modules that are initiating the theme layer prematurely.

The clues.
1. Submitting a form works fine. I'm building a search engine application and I get the initial screen (with the form), and I can get the form.
2. Here's a link that works:
http://apps.facebook.com/sheet-music-devel/search/sheetmusic/test?filters=instrumentation%3ABass&_fb_fromhash=877cb895801c9bf9e7b60ea057e8939c3. Here's a link that breaks:
http://apps.facebook.com/sheet-music-devel/sheetmusic/5854274/test?_fb_fromhash=877cb895801c9bf9e7b60ea057e8939c#4
More clues.
This link doesn't work:
http://apps.facebook.com/sheet-music-devel/sheetmusic/5854274/test?_fb_fromhash=877cb895801c9bf9e7b60ea057e8939cThis link, without the _fb_fromhash param, DOES work.
http://devel.presto-sheet-music.com/fb_cb/1/sheetmusic/5854274/testInterestingly, these are both showing up in the canvas page.
The two links are being produced like this:
<?php$v['link'] = l($v['title'], $v['url'], array('absolute' => TRUE));
if ($v['imageurl']) {
$v['image'] = l(
theme('image', $v['imageurl'], $v['title'], $v['title'], array('align' => 'left', 'style' => 'padding-right: 1.5em;'), FALSE),
'sheetmusic/' . $v['id'] . '/' . search_get_keys(),
array('absolute' => TRUE, 'html' => TRUE,)
);
}
?>
That's a bit hard to read, but the essence is that both go through l(), both with 'absolute' => TRUE. Why does one get the _fb_fromhash and the other one doesnt? And why is this _fb_fromhash screwing with the working of the code?
#5
Perhaps the final clues, and then a mystery.
My code, in both cases above, ends here:
<?phpheader("Location: $url") ;
exit();
?>
It reaches this point, in both cases, with exactly the same value for $url. However, the variation with the _fb_fromhash fails (sends the output back to facebook as a broken canvas), and the version without the hash succeeds.
So the mystery is, why?
#6
Forget everything I wrote. The error was mine. I was trying to go to an external link but was not using an absolute URL.

ravdeepchawla, are you still having a problem, or was it the same site?
Robert, Let me know about your app when it is ready. I'm curious what you're up to with these modules.

Dave, sent you two mails using your contact form, without reply. Perhaps into the spam bucket? Please contact me via email. Thanks!
