[ckan-dev] Error adding custom field to organization (IGroupForm)

[lucia.espona at wsl.ch]

Dear all,

I am trying to add a custom field to the organizations extending the IGroupForm. I cannot use ckanext-scheming because I am modifying ckanext-hierarchy.

I pasted below the error I get when trying to view an organization and the plugin code below. If someone has added a custom organization field, I would be grateful if he/she can share the code with me.

Many thanks in advance,
Lucia
