Multi-Select Lookup

Multi-Select Lookup

Hi,

I have a multi-select field in Deals that links to a custom module "Devices". I'm trying to write a function that updates all devices related by this lookup field, however, I have no way of getting record IDs or other identifying info for all the related records.

The custom module is not supported by the getRelatedRecords() function. Calling get("Lookup_Field_API_Name") on the record returns a string of what is displayed rather than a list of IDs like I was hoping (i.e. "related_record_name_1, related_record_name_2, & More"). This is enough to identify two related records but nothing else. Am i missing something? Or is this functionality completely absent for multi-select lookup fields?

Thanks,
Nathan
