Thanks for looking into it. I'm not sure what the issue is. If it works for everyone else, I guess that's good enough. Thanks again, Greg On Mon, Jan 30, 2012 at 6:53 AM, Brad Chapman <chapmanb@50mail.com> wrote:
Greg; I've been looking into this and am unfortunately still not able to reproduce it. It seems like the setTimeout in the javascript code which calls the function until the state becomes 'running' is not being correctly run. There are some bugs out there with older versions of Firefox and Firebug:
http://code.google.com/p/fbug/issues/detail?id=3245
It might be worth upgrading and see if you still have any issues since it does seem to be working smoothly on current Firefox versions.
Hope this fixes it, Brad
Hmm, I just launched again (I had Firebug enabled and JS started paused). When I unpaused it worked.
It's looking more and more like it's making a call to the GET URL too quickly and getting back some kind of bad value that's throwing off the javascript logic? Undefined? That's my best guess at this point.

Hi Brad,
I tried again just now.
I launched and left it alone for 5 minutes. It said "not available" in the Instance State cell. And nothing else happened.
Then I ran this in Firebug and it did fill in the proper information on the page:
update_instance_state(); GET http://biocloudcentral.herokuapp.com/state 200 OK 171ms undefined running
I'm not sure where that "undefined" is coming from. Maybe that is part of the problem? It seems like update_instance_state() isn't being run.
I don't have anything blocking JS.
Here's my system/browser info:
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.25) Gecko/20111212 Firefox/3.6.25
By the way, it might be a nice touch to put loading icons next to the cells in the table that will get updated. There are some here: http://www.ajaxload.info/ The Javascript function could just remove or hide the icons once the final info is loaded.

Greg; As you dug into, the javascript function should keep refreshing and checking the state until the information is available from the EC2 console, and then fill it in. This does work for me as intended on Firefox 9.0.1 and Chrome. It normally takes a minute or so for the server information to be available from Amazon.
Are you seeing the failure to refresh and fill in the information every time you use BioCloudCentral or intermittently? Do you have any javascript blockers or other magic running? Anything else that might help with reproducing this?
Thanks for letting us know about the problem and hopefully we can get it sorted out, Brad
Ok, I did some more investigating.
After I launched (5 minutes later if it matters), I opened up Firebug and ran "update_instance_state();" and it did fill in the information.
Maybe there's something wrong in the JS logic? Is it setting the state to running before it has the information?
Here's the javascript for easy reference:
<script> function update_instance_state() { $.get("/state", function(data) { console.log(data.instance_state); if (data.instance_state != '') { $('#inst_state').html(data.instance_state); } if (data.instance_state != 'running') {
window.setTimeout(function(){update_instance_state()}, 5000); } else { $('#ssh_public_dns').html(data.public_dns); $('#nx_public_dns').html(data.public_dns); $('#cloud_url').html('<a href="http://' + data.public_dns + '/cloud" target="_blank">' + data.public_dns + '</a>'); } }); } $(document).ready(function() { update_instance_state(); }); </script>
Thanks,
Greg

Hi guys,
When I launch using BioCloudCentral (http://biocloudcentral.herokuapp.com) I noticed it doesn't show my public DNS. Even if I wait for a few minutes.
For the "Public IP (Cloudman Console)" table cell, it just shows blank, and for the SSH access area is just says "ssh ubuntu@"
It hasn't been a big deal because I just pull it from my EC2 console. But now I'm writing up some documentation for other researchers to use our application running on CloudMan, and it adds a lot of complexity to the documentation to tell them to log into the EC2 console, click on instances, copy the public DNS ... It would be excellent if they could just click a link from the launch page!
Let me know if I can help with debugging.
Thanks again,
Greg
