How LiveCycle Forms ES prepopulates formsLiveCycle Forms ES can prepopulate a form with data from an external data source while the form is being rendered.For some simple applications, by setting up data binding in LiveCycle Designer ES, you may be able to create forms that work with external data without having to write a script. Binding alone can usually be used to obtain data from a WSDL data source or an OLEDB database.LiveCycle Forms ES provides support for simple data binding. Simple binding enables you to bind a single value to a field.
