#15 EntityValue.update causes NPE

[Vasanth Kamatgi]

If the new value of a field of an entity is the same as the old value of an entity, calling update() causes an NPE. Here is an example code snippet.
def exampleUserAccount = ec.entity.makeFind("UserAccount").condition("username", "example.viewer").one();
exampleUserAccount.userFullName = "Example Viewer";
exampleUserAccount.update();
Here is the stack trace.
java.lang.NullPointerException: Cannot invoke method values() on null object

....

The solution might be adding the null check at line#385 in EntityValueImpl.groovy
if(dbValueMap) for (Object val in dbValueMap.values()) if (val != null) { dbValueMapFromDb = true; break }
