LS,

I have changed a lot of files making vlan a broadcast uri instead of a numb=
er. I have probably broken something or in the best case omitted a needed c=
hange to complete this. The result is a null pointer exception during the c=
reation/connecting of a vif:

Now I want to track back to where this ip is created to find out why it doe=
s not contain a mac-address. Looking in the database it does contain a mac =
address. I am guessing someone knows or can give me a pointer; What in the =
above stack can lead to the provisioning code that I should adjust?

Thanks,
Daan Hoogland
