Hi,
I'm trying to expose/promote the Group parameter of a node inside a subnet/HDA so I can manually select points from the subnet/HDA exposed/promoted parameter. It works if we type in the values manually or select a group from the list, but as soon as I click the little arrow to make a manual selection, Houdini pops up a “argument of type ‘NoneType’ is not iterable” error message. What's going on? How can I make this work?
Click arrow on the exposed Group pararmeter in a subnet/HDA gives error...

In the action button tab, replace the script with, the following and replace “keepMe” with the name of the node
import soputils
path = kwargs.path()+“/keepMe”
#keepMe is the name/relative path of the node we want to actually use.
kwargs = (hou.geometryType.Primitives,) #fix this for selection type
kwargs = hou.node(path)
kwargs = 0
soputils.selectGroupParm(kwargs)
import soputils
path = kwargs.path()+“/keepMe”
#keepMe is the name/relative path of the node we want to actually use.
kwargs = (hou.geometryType.Primitives,) #fix this for selection type
kwargs = hou.node(path)
kwargs = 0
soputils.selectGroupParm(kwargs)

Hi,
I have the same issue,but now I solved it.
The original group nodes has the action button script is :
If you want your hda has the same feature, you need to modified the script like this:
I hope it's helpful

If you want your hda has the same feature, you need to modified the script like this:
import soputils node = kwargs['node'] path = node.path() + "/split1" //the group node in your hda split_node = hou.node(path) //the group node in your hda kwargs['node'] = split_node //modifies the kwargs argments 'node' kwargs['geometrytype'] = kwargs['node'].parmTuple('grouptype') kwargs['inputindex'] = 0 soputils.selectGroupParm(kwargs)
I hope it's helpful

you don't need to reference or even have internal node that also uses group:
just either specify “grouptype” parameter on your HDA or define the type internally

import soputils kwargs['geometrytype'] = hou.geometryType.Primitives kwargs['inputindex'] = 0 soputils.selectGroupParm(kwargs)
