can store only one int in setAdditionalNodeField, but I would like to use both the TurnCostStorage and the OsmIdsExtendedStorage.

Since osmIds are of type long but the additional fields for edges and nodes are of type int, you have to use additional storages and let the additional fields point at its entries. I think Peter can tell you where you can find helper methods in order to split a long value into two integer values. But you're right, looking at my code in TurnCostStorage should help you. Fell free to ask if you have further questions.<br clear="none">
