Message: Call to a member function format() on null

When I try to edit the customers in the admin site I get this message.
Error reporting is on maximum.

Hello,

Can you give us more information about your error message through screenshots for example ?

Thank you.

See attachment for error dump (

).

I see following behavior.
Joomla user who is customer without any address; no problem
Joomla user with address I get the error as shown in the screen dump.

The default address is created by a code / plugin written by myself (only members of our club are allowed to use the shop).

Will check today with a user + address created by hikashop and will come back to you.

I made a new order for a new customer.
In the admin site I get the same error message as with editing the customer for a club member.

Nicolas,

It was slightly different.

The Koowa component came with Docman, bus is not required anymore.

What actually was the case is that I made an override in the admin site (com_hikashop/user/form.php) why I cannot remember.

By removing this override the problem was solved.. I suppose I have to invest of the use of this override.

Anyway, you pointed me into a direction to solve the problem.

Thanks!!
