ZenDesk is a third party customer support tool that integrates with Salesforce.Because they had a bug with their customizations, I wrote a scheduled class that went into their custom records after they were created, and updated some information in them. I didn't make the class part of their package or anything like that AFAIK.
Recently I noticed a date-sensitive test had failed in its test class, so I downloaded the class and its test class from my production into the IDE so I could update the test and redeploy.
Here's the strange thing: when I check the xml file of those classes, they both have tags similar to managed package classes! None of my other classes have this "packageversions" tag
While all the ZenDesk file names start with ZenDesk, mine starts with "Scheduled", so I'm not sure if my filename is the cause. And when I look at the class within SF.com, it clearly doesn't have a namespace:
Can anyone explain what's going on here?
