<scott> jsled: I have a customer issue, where their MEM graphs present old data
<jsled> how old is old?
<scott> The small graphs keep up when they click a different server
<scott> but when the click a graph, the large image shows the previously selected server
<jsled> this is on the dashboard, then?
<jsled> I believe we're not as clean as we should be in re-using that popup on the dashboard.
<scott> yes
<scott> however, they see the problem in Firefox, but not in IE
<jsled> Specifically, if you open one larger graph, then dismiss the popup, then open another, we don't first clear out the old image.
<scott> that sounds like it might be related. Any workaround?
<jsled> Plus, since it's a dynamic image replace, the browser's spinner isn't going.
<jsled> I'd guess that it's just taking "a while" for the correct image to replace the invalid one.
<jsled> Could verify with firebug or a network trace or something, but I'm pretty confident that's it.
<jsled> "Reload the dashboard" is a heavy workaround.
<jsled> but that will re-initialize the popup to empty.
<scott> yes, the customer already firgured that one out on their own
<jsled> Otherwise … wait a bit longer. :(
<jsled> And we'll file a bug; I'm changing graph serving in 2.1, so I'll make sure to address this in the course of doing that.
How to repeat:
load dashboard. popup larger graph. dismiss graph. popup different graph. Notice you see the first graph, hopefully for only a very brief time until the correct one loads.
Suggested fix:
Blank out the image (or, better, always display a "loading" spinner) on showing the popup.
