Nevermind. I've got it.

It seems that the issue is not FF 4 or jqgrid but instead: the firebug extension.

You have two options, turn it off to see this page or as it says here:

"Please try with Firebug > Console > mini-menu > Show XMLHttpRequests OFF."

Thanks,

Ernie

Here's how it works once you disable the Show XMLHttpRequests option in Firebug:

Whatever the problem i'm having is, it can't be related with firebug because my test machines don't have firebug installed and they don't render the gradebook in FF4, but they do in FF3.6, only my development machine has it.

Test machines:
#1: Windows7 + FF4 (no plugins)
#2: Windows XP Professional SP3 + FF4 (no plugins)

Server:
Linux + LAMS 2.3.4

Thanks,
Helder

Hi Helder,

It works for me as you can see in the pic. Can you clear your cache just in case?

Thanks,

Ernie

It's not cache related.

In the mean time i've noticed that if i refresh the gradebook page it will eventually load ok, but it's like in 10 refresh will work twice. It really strange, seams something around the load timings of the js files. But this only happens with FF4, all other versions of FF and IE work ok.

Do you have an online demo version of LAMS where i can test gradebook? Or else i'll need to fresh install a new server to try to replicate this.

Thanks,
Helder

Thanks Ernie.

I've made the test and got the exact same problem, but with a little variation, which makes my suspicion about load timings even stronger.

Here's the test case:
1. Using FF4 goto http://translations.lamscommunity.org/lams and login
2. Select "Mark" in one of the lessons.
Result: Most of times will open correctly but sometimes grid doesn't show (in my case 1 failed out of 10).

3. Press F5 (refresh)
R: The grid will not open.

Why this makes me think on a problem with the load timings (maybe the order of js load) is because, when the page loads slow (in my case using your site.) it works when it loads fast (F5 will use cache) it fails. In my scenario fails more times because i'm connected locally in the server, so it loads really fast... Well it's just a guess.

This doesn't happen in IE or FF3.6

Thanks,
Helder
