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

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':

https://wiki.eprints.org/w/Dataobjref_field

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

Dear all

Just add a new dataset - campuses to our repository. The type is subject. I already run epadmin update dan upgrade.

However, when I add <component><field ref="campuses" /></component> in our default page, it will show an error with the log indicated as below:
