Hi I am trying to use the getGUID command from community commons to retrieve the GUID from several objects to get an unique reference id. The methode should result an integer, however i cannot store the data in a integer field; it seems it needs a long field to store the value. for a couple of entities this works. For some other entities i get an error: Invalid JSONRequest: Value 12666373951980821 out of range for javascript. In a long 2^63 should fit (9223372036854775807), so that shouldn't be the problem. How to deal with this? regards, Pieter
