Hi community,

When I assign an existing Category (priority 2) to an existing Parent (priority 1), the system throws an exception: “LogicException: Node must exists.” with stacktrace of approx. 60 lines (I will add this to the end of my post).

I have currently a shop configuration with 2 geographic locations. Just to be sure, I tested with following scenarios:
a) Checked the administrator’s account details and made sure this account has rights assigned for both locations - fails
b) Parent and Child category both assigned to single (and same) location - fails
c) Parent and Child category both assigned to both locations - fails

The error does NOT occur for newly created Parent- and Child Categories, but the result is much worse as it broke my end-user web-page, here is what it looks like:

Here the stacktrace when I try to establish Parent/Child relation for existing Categories:
