Base Field Detail Refresh

Hello community!

I need your help.

I'm using a BaseFieldDetail like the sample in the academy:

https://academy.bpmonline.com/documents/technic-sdk/7-11/creating-custom-detail-fields

the problem is that my mastercolum is not the Id of the record, is just a column with a related contact.

i need reload/refresh the detail when the contact change for another. I did try with loadDetail() because the reloadDetail is obsolete but not refresh the data.

Any Idea?
