Hi,

I'm trying to create a Rollup SUM on a master object to total a number formula field on the child records, but it's not letting me select the field to SUM.

The formula field on the child record references a related object. Is this the reason it will not let me select that field to SUM? 

I need to get a lookup ID from an inputField component via JavaScript but the field with the lookup ID looks different and I can't rely on setting a static component ID to get it.

Is there anyway I can do this? I'm developing a managed app, so I need to be able to make sure I can get the ID of the field dynamically.

Being that when I try to define a parent-child relationship the object itself isn't offered, that would imply the SFDC doesn't support self-relationships.  Correct?
