I am having a problem getting data from the National Weather Service's "National Digital Forecast Database" XML Web Service... http://www.weather.gov/xml/ <http://www.weather.gov/xml/> . I',m using Flex Builder 2.0.1.
The service provides 9 functions for accessing the NWS' vast database of weather forecasts and statistics. I am able to use the simplest one, "latLonByZipCode" with no trouble... I pass it a valid US zipcode, it returns a string containing the corresponding latitude and longitude. I pass it a bad zipcode, it returns a nice, informative error message. When I try one of the other functions (NDFDgenByDay), I keep getting the following: "TypeError: Error #1009: Cannot access a property or method of a null object reference", triggered by the webservice call. The errorID i s 0, the fault code is "Encoding Error", and the message is null. The only difference I can see between these 2 function calls is the list of input parameters -- latLonByZipCode (the one that's working) takes a single string argument; NDFDgenByDay takes a mix of decimal, date, integer, and string arguments. Could an ill-formed argument list cause this error? (and if so, what do I need to do to fix it). Any help would be greatly appreciated!
