Currently, any property type int or long, set to 0, will show up in the Properties Management tab as blank. This then will result in errors when trying to change values of other properties, etc.

The problem is caused by a test for getProperty in properties.dtml. If it returns false, it won't display the value. If it would test for hasProperty instead, the property is correctly displayed.

Here is a diff:
diff -r1.29 properties.dtml
46c46
<    value="<!--#if "getProperty(id)"--><!--#var "'%d' % getProperty(id)"--><!--#/if-->">
---
>    value="<!--#if "hasProperty(id)"--><!--#var "'%d' % getProperty(id)"--><!--#/if-->">

of things up (in preparation for the move). Rearranged things,
moving alot of code out of Globals into other modules.
Migrates some modules into packages and did away with the
infamous Scheduler.

Hold on to your butts. ;)
