Error on Zone setting page

[omriasta]

When going to the zones page in settings, (https://alarmdecoder/settings/zones/) I am getting the error below.
Alarmdecoder is installed using the preconfigured pi image. The keypad is able to interact with the panel. The error starts as soon as I scan the panel for zones. Once I do that, it completes successfully and lists all the zones but next time I try to go to the settings zone page it gives the below error. The rest of the webapp is still working fine.
What could be causing this? Also, is there any way to reset the webapp so I don't have to reimage the pi?
THANK YOU IN ADVANCE!!!

It must be picking up some unrecognized character in the stream - maybe you should configure your zones manually

You can reset the database by sshing into the pi and doing these commands:

cd /opt/alarmdecoder-webapp
sudo rm instance/db.sqlite
python manage.py initdb

So, first of all I found the sqlite.db that needs to be deleted to reset the db and was able to get back to the zones page.
I also noticed that when retrieving the zones from the panel there were 2 zones with abnormal characters in their zone id. I updated their zone_id in the sqllite db and was able to get into the zones page again. Not sure if anyone can fix the webapp to detect these characters and warn/change them so it doesn't cause the crash? Any idea why my panel would have these odd characters?

Sorry, the AUI protocol scanning isn't perfect so there might be an issue here and there - I could only test on the panels I had available, so there may be some things unexpected - but yes it is possible to adjust the code to filter out those characters - editing the database is a good solution to your problem currently

Took a stab at fixing this and just created a pull request in github.
Looks like the issue has to do with the way the zone aui message is parsed. It was not accounting for double digits with 0 in them i.e zone 10, 20, 30 etc. Hopefully my change makes it in, and helps out.
