Bug "Too much recursion" #9
Description
There is a bug caused by a weak check using recursion to list all child forms errors in the same form-errors panel.
We have encountered this because of angular-xeditable but I'm sure it's not the only case that can occur.
The problem is simple: this directive search child forms between props not starting with dollar "$", but xeditable put some internal props starting with "_" which breaks the recursion. To solve this problem I've made a fork checking if the value of the property is an object before recursing.
