I get an error when I have a group node inside my OTL and I expose the "basegroup" parameter and try to select points on the OTL controls, I want to be able to select points for a group.
Traceback (most recent call last):
File "Parameter Scripted Action", line 4, in <module>
AttributeError: 'NoneType' object has no attribute 'eval'
Can anyone fill me in how to get this working?

it's because you are promoting only "basegroup" parameter but still using it's Action Button script on promoted parameter:
which as you see tries to find on 'grouptype' and 'ordered' parameter and can't so it errors out
so you can either promote those parameter also, if you want to have choice
or just alter the Action Button script and hardcode the ones you didn't promote to specific value:
import soputils kwargs['geometrytype'] = kwargs['node'].parmTuple('grouptype') kwargs['inputindex'] = 0 kwargs['ordered'] = kwargs['node'].parm('ordered').eval() soputils.selectGroupParm(kwargs)

import soputils kwargs['geometrytype'] = hou.geometryType.Primitives # or hou.geometryType.Points etc... kwargs['inputindex'] = 0 kwargs['ordered'] = False # or True soputils.selectGroupParm(kwargs)
