Hi, Im trying to create a new address line on a customer but I keep getting an

TypeError: Cannot find function setSublistValue in object dynamic record.

What Im doing is loading the customer record and trying to set the values I tried changing the loading dynamic to false but it also gives me the same error just with standard mode, the thing is, this functionality is on a function that it works when the new line is created when on the same record, thats why I thought I could reutilize the function with a loaded record haha
