I have managed to set the '__fold' to True in the _read_group_fill_results() function for the Kanban states I wish to fold in my model.py file.

def _read_group_fill_results(self, domain, groupby,
​remaining_groupbys, aggregated_fields,
​count_field, read_group_result,
​read_group_order=None):​

​results = super(myModelClass, self)._read_group_fill_results(
​ ​domain, groupby, remaining_groupbys, aggregated_fields,
​ ​ ​count_field, read_group_result, read_group_order
​) 

​for result in results:
​ ​state = result['status']
​ ​result['__fold'] = state[0] in THE_LIST_OF_FOLDED_STATES

​return results

The THE_LIST_OF_FOLDED_STATES is populated from a Javascript function that calls the Python through a rpc.query call.

rpc.query({
​model: 'my.model.class',
​method: 'kanban_folded_state',
​args: ['in_progress','actioned'],
})

This calls kanban_folded_state in the model.py file.

@api.model
​def kanban_folded_state(self, *folded_states): 
​global THE_LIST_OF_FOLDED_STATES
​THE_LIST_OF_FOLDED_STATES= folded_states[:]

However, the actual Kanban view on the webpage doesn't reflect the folded state, unless I refresh the webpage (F5).

What I would like to do is to force the Kanban View to reflect the folded state for each stage programatically through Javascript following the rpc.query call.

Thanks,

Simon
