Topic: Widget crashes upon unloading?

Hey, Chumby programmers!

So I'm looking into the crashing Kotaku widget (yes... finally...), and I was able to capture the log at the moment when it crashed. As far as I can tell, it seems like things are going okay until it tries to start up the next widget (Lifehacker, in my case), and then unload the old Kotaku widget. That's where things get really screwy.

Has anybody seen a crash like this before and know what it means? Is there something I'm not cleaning up correctly with the old widget? I'm kinda at a loss here.

Re: Widget crashes upon unloading?

It looks like a problem with a cancelled HTTP request after the corresponding player instance has been destroyed.

I'll forward to the developer.  Thanks.

I am the developer. smile

So my widget works a little something like this...

a) Display the current story.
b) Attempt to load the image for the next story while the first one is still being shown.
c) Receive the image for the next story.
d) When the next story is ready to be displayed, show the image that I have loaded in the meantime.

So is the problem that if widget is getting destroyed somewhere between b) and c), bad things happen? Is there a crucial clean-up step that I'm neglecting?

No - I meant the developer at Chumby who maintains the Flash Lite Player.

Well, if it's something I need to fix, please let me know.

Thanks!

Re: Widget crashes upon unloading?

OK, it appears we fixed this particular bug a while back, so it will come along with one of the firmware updates.

Unfortunately, there's nothing you can do at the widget level.

No worries. I'll just wait for the next firmware update and, assuming everything looks good, I'll make the widget public again. (Any idea when that might be, incidentally?)
