Manos,
We agree, it's an issue. Coincidentally, Facebook just put out a developer blog post regarding this issue, stating how difficult it is to 'shrink' a page. They actually can't fix it, and their solution is simply to rename the setAutoResize funtion to setAutoGrow so that the actual behavior is less confusing.
developers.facebook.com/blog/post/565/

Their recommendation is that on dynamic pages, to use the setSize function, but in that case, you'd need to know the final height ahead of time.

This affects us too, and we agree it isn't great, but it's the best that can be done in a dynamic Joomla environment. While we've heard this request once or twice from admins/subscribers, we've never heard issues from end-users. I think it's something that admins catch and see more than actual users of the page because they know what should be happening vs what actually is.

Hope that helps explain,
Alex

Hi Alex,

So what you tell me is that the solution is, there is no solution? :D
Is there a way to know the size of each of my page? And if yes, could there be a script that would resize the page accordingly?
My first concern if not the mess with your component, since I see that it stops working when I have an other part of code using Facebook API.

Kind regards,

Manos

There really isn't a good way to know the height of your page. Since the height can change dynamically by Javascript running on the page itself, it would have to be a constant check to see what the height is, and resize to that, which could cause a lot of 'jumping' around in the browser. Additionally, every browser is different, which means heights aren't always the same, which means compatibility is another issue.

Basically, if Facebook is throwing in the towel on trying to get 'shrinking' to work, it's a good indicator that there isn't a magic bullet to get it going.

Hope that makes sense,
Alex

It appears that auto expanding does not work either. I created a quiz which contains a lot of picture hotspot questions and the result is a long results page at the end. However the page is cut at the height of the home page. This is a huge problem as you can imagine.

First you have to login with facebook. Then from the main menu, navigate to Contests / Christmas 2011 / Quizzes and Play the Intermediate Quiz. After the end of the Quiz, you will see the results. Either choose to display 15 instead of 5, or change the page to see the page that has the most hotspot questions.

Thanks

Did you by any chance take a look at it? Because I have to release the site to be live on October 1st.
Thanks

Manos,
Just tested, and can see the problem. Still not sure of the cause, but if you could, please try the following code modification. In the /plugins/system/jfbcsystem.php file, around line 140, you'll see:
if ($this->jfbcCanvas->get('resizeEnabled', false))
            $resizeCode = "window.setTimeout(function() {\n" .
                          "  FB.Canvas.setAutoResize();\n" .
                          "}, 250);";
        else
            $resizeCode = "";
Simply comment out the if/else portions (leaving the $resizeCode block as is), so it looks like the following:
// if ($this->jfbcCanvas->get('resizeEnabled', false))
            $resizeCode = "window.setTimeout(function() {\n" .
                          "  FB.Canvas.setAutoResize();\n" .
                          "}, 250);";
        //else
        //    $resizeCode = "";

Basically, what we're seeing is that the setAutoResize function isn't being set after we login through the Canvas. It's possible this is a bug with JFBConnect, some behavior of Facebook we weren't aware of, or something else completely. We'll have to investigate more, but if you can let us know how that works out for you, it will help us out a lot... and hopefully get you ready for Oct 1st.

Thanks, and good luck,
Alex

That did it! Check it out for yourself. So what is the problem? Am I supposed to leave this fix? What will happen with the next update?

Thanks man. :D

Leave the fix. It shouldn't cause any problems and is simply something we'll have to look into for the next release. It seems like the act of logging the user into the site through Facebook causes issues with our Canvas page detection. It should be easy for us to recreate, but don't know anything else right now.

Good luck,
Alex
