Phuc Nguyen 18 Illegal assignment error
I am getting an errro with my code:
Illegal assignment from List<sector__c> to id
What I am trying to do:
When a Candidate is made Primary, the Sector Record's Site Lookup field should get populated with the Site record that is linked with the Candidate record.

Can you try the above changes once and beware that I am assuming that in the list of records the necessary record is first so I am taking only that particular record and assigning the id if not then you need to check each record and get the id of the record that satisfies your condition.

So the error in this line sector.Site__c = m_sitesToSectors.get(newCandidate.Site__c); is that the m_sitesToSectors has a key as id and the value as a list of records List<Sector__c>, also I think Site__c is a lookup field for the object sector, to assign a value you will have to get the id of the record and then assign the id to the sector.Site__c.
You can do Something like the below:
Sector__c sRecord=m_sitesToSectors.get(newCandidate.Site__c)[0];
sector.Site__c = sRecord.id;
sectorsToUpdate.add(sector);
Please make changes as per your requirement.
Let me know if it helps you and close your query by marking it as solved so that it can help others in the future.
Thanks.
You are corretc. teh Site field is a lookup. Code saves and dseployed but getting a 'Message[Attempt to de-reference a null object' error whne I go to update/save a record. But not seeing error message in my debug log.
Eventhough I know there is a value there(in a test org). Why am I mot getting it?
Sector__c rec = sRecord[0];
sector.Site__c = rec.id;
sectorsToUpdate.add(sector);
