Upgrading to PW3 / Page Reference Field (PHP Custom Code) Problem

[Orkun]

Hi Guys

After upgrading from 2.7.3 to 3.0.141 I am getting following errors when editing pages that have a page reference field with php custom code option enabled.

 

On the corresponding page/template I have these two fields/custom code:

 

I have tried to solve it by adding

namespace ProcessWire;

at the top of the custom code (for both pagefields) but that doens't worked. The error still persist.

How can I solve this?

Have you cleared the modules cache and the compiled files?

I already have but it didn't helped.

Nevermind. There was a repeater inside the template which also had a pagefield with custom code in it. :D
