This should hit a servlet registered by resource type, but the page doesn't exist, resulting in a constraint violation while trying to create the node. It looks like the page was moved to /apps, but the form post location was never updated to match.

Looks like the javascript client library was pointing to the old /etc location and wasn't updated when we moved the page to /apps/acs-commons. Fixing now.

Thanks @shsteimer! I posted a fix to the master branch.
