[otrs] otrs 3.1.4 templates for To and cc

Hi all, Just updated from 3.0.9 to 3.1.4 and cant get the templates working. The To field is no longer using "CustomerID" value="070808126150280643214C"/> "SelectedCustomerUser" value="97556"/> to be able to select the correct user from the correect company. It now seems you should use "CustomerKey" or "CustomerKey_1" but i cant for the life of me get it to work. anyone managed to get passed this hurdle or knows the correct name? Also CC is now no longer a text field either and works in much the same way. If i can get To working i can figure cc out later. thanks Neil
