In purchase contract -> General tab -> Suppliers -> Add 2 supplier and select the first of them as primary, Add a third row of supplier and do not fill the mandatory fields! Go to the other suppliers, select the second supplier as primary. <o:ajax listener="#{contractGeneralSupplierController.supplierPrimaryChanged}" event="change" ... When you change the 'primary' field the 'supplierPrimaryChanged' function need to be called But in this case it does not happen
