Hello Olivier,

Take a look at the script action. It is automaticly created when you promote the baseGroup parameter. Assuming you promote your parameter "from node" or by "drag and drop".

Edit the HDA parameter interface, select the base group parameter and look for the tags parms. Look at the script action.
It look for the "grouptype" parm and "ordered" parm parm by default. Promote those twoo parameters it will work. If you change the parameters names you will have to edit the script_action according to the new names.

hope this help

Objet: [Sidefx-houdini-list] Houdini problem with edit parameter interface for group "BUTTONS_reselect"

Hi quiet list :)

I've made a super simple HDA where a group of point needs to be selected to
create a group.

In edit "parameter interface" I exposed the Base Group, but the little
arrow "BUTTONS_reselect", when is clicked, gives this error message :

Traceback (most recent call last):
  File "Parameter Scripted Action", line 4, in <module>
AttributeError: 'NoneType' object has no attribute 'eval'

I guess there's something to tweak in the tab "action button" ?

If someone can help..
