I had a look at the code for this function (I work for Cadence), and I can't see how it could omit any pin - it looks at all the terminals in the cellView.
Are you sure all the pins really were pins? (i.e. they weren't just shapes with text labels above them).
If you do:
Code:geGetEditCellView()~>terminals~>name
It will list all the terminals in the current cellView.
