This flow service evaluates a Domino formula. If the formula contains the name of a field, you must use the second method parameter document. The formula takes the field from the document specified as parameter document. Functions that affect the user interface do not work in evaluate. These include: Command, DbManager, DbName, DbTitle, DDEExecute, DDEInitiate, DDEPoke, DDETerminate, DialogBox, PickList, PostedCommand, Prompt, and ViewTitle. You cannot change a document with evaluate; you can only get a result. To change a document, write the result to the document with a method such as Document.replaceItemValue.
