How to get ConnectorSet or Connectors from FamilyInstance correctly?

[gnab]

Hello, everyone. I can't get ConnectorSet of FamilyInstance. I did almost the same thing like with Pipe but I got the Exception with FamilyInstanse. I tried also to get Connectors with LookUp method but sometimes I got the same Exception again. Why? How to get ConnectorSet of FamilyInstance correctly?

I think I can beat it. After placement of FamilyInstance you need to do doc.Regenerate() and then get Connectors from ConnectorSet with foreach cycle and creation a list of connectors. ConnectorSet and Lookup of FamilyInstance doesn't work correctly (ConnectorSet or one of Connectors provoke the Exception)..It's not normally, I suppose, because all of these methods work very well with Pipe but not with FamilyInstance. Devs should fix it.
