Multiple Intermittent Null Value Exceptions

Postby whornak » 20 Oct 2010, 10:46

Win XP, FlashPayer 9.0.283.0 debugger, SFS 1.6.9, Opens Space 2.0.2, IE 8

I can manuever from map to map without issue but on occasion and to this point without consistancy, will continue to look for that, experience the following errors. They don't seem to have an effect on functionality once continue is hit in the notification. Wanted to post to see if either of these had an obvious cause of some direction could be provided as to the cause.

getting these errors too when i aggressively click around tiles closer to the borders, and the avatar will get stuck in a loop.

This has been reported by other users too, even if it it seems we are not able to reproduce it. Are you able to record a video showing the behavior? Having the tiles grid displayed would be useful too.

Also, are you able to provide more details on the issue? Do you see it happening in special conditions? For example if the avatar is causing a scrolling, when other avatars are moving around too, or when the avatar is alone, etc? What if you have 2 clients showing the same map? Does the error happens on the client of the user who is clicking around? What happens on the other client in this case?
We are looking for a "pattern" to make this issue more reproducible, because in our test maps we can keep clicking around as long and fast as we like, but it never happens.
Is the issue occurring in the live environment only, or in you dev environment too (maybe it is related with lag)? Is your map design peculiar? I mean, a lot of non walkable tiles among the walkable ones?
What are your avatar settings? For example, do you set the Avatar.controlAreaWidth property? Thank you.

It appears to only occur on my live server, not on localhost. Quite easy to replicate but am unable to provide a screen cap of it..

The error occurs when I click multiple times on the same border tile while the avatar is walking toward it.

No scrolling involved, just a small map.
Occurs to any avatar, regardless of number of avatars in the room.

Avatar.controlAreaWidth = 0

Not sure how else I could provide more info..

Thank you for the additional informations.
It would be really useful for us to actually see the avatar behavior during the movement. Is it possible to access your live environment and see this on our screens?

unfortunately i cant provide any further detail.

is there a temp workaround that I can do, like disabling tile clicks while the avatar is walking, to prevent a change of coordinates?

I just sent an email to support with some creds, it's pretty easy to duplicate...basically you just need to click around the map quickly and either the debug window will pop or the screen will lock.

While performing the test w/Marc, I was not able to cause the error but did experience an 1009 issue noted in the beginning of this thread. What I did was simply log in and nothing else, no movement at all. Watching Marc moving around and changing directions until I get the flash player exception window. Once that happened I hit continue or dismiss and his avatar is walking in place until it disappears. Each time I experience the error I can continue as if nothing happened.

hopefully some good news as well for this...this has been killing our testing for a couple weeks now.

We are investigating the issue. We are still not able to reproduce it in our environment, but we are receiving the help of a number of customers, so hopefully we should be able to fix it soon.

You could use the IOpenSpace.userInteractionEnabled property, but then setting it to true again when the avatar stops moving would require having a proper trigger added to each tile. Not a good solution. We suggest to wait for the bug fix.

We think we have found the problem, and possibly solved it.

All those who experienced the issue should please contact us by email, so we can send a pre-release version for some testing in their environments.
If you are OpenSpace customers, please attach the invoice to the email, so we can send you the retail version.

Customers who are not able to reproduce the issue, please wait the official release, thanks.
