[EP-tech] {Suspected SPAM} Undefined or invalid function when add new dataset field

[drn at ecs.soton.ac.uk (David R Newman)]

Hi Izwan,

You say that campuses is a new dataset but you have added the field as 
type 'subject'.? This is not going to work you probably want to use type 
'dataobjref':

If campuses are actually specified in your subjects tree then you could 
use a field of type 'subject'.? However, you would need to make sure you 
have section of you subject tree that contains all your campuses and 
then specify this parent subject's id this under the 'top' attribute of 
the subject typed field.

Regards

David Newman
