and also in the "ir.ui.view" for the higher priority: field name="priority" eval="15"

Setting the eval to 15 makes client_form_view_2 a higher priority (the default view), but I thought you were saying that only the one with eval=15 was showing. Again, the only difference between the two actions are that client_form_action calls the default view and client_form_action1 specifies a view_id and that "overrides" the default view.

ok for the form view it works without priority, but for list graph gantt kanban its not working at all... how is it possible to use the "REF" for lists or even better for customized lists derived from list of the web module.

Peter,

As far as I know, without using the "views" option in some python code, you can only specify a single view_id or set the priority like you did originally to get the views you want by default.

Look at the answer here for an example of how to specify the views for all view types using python code:
http://stackoverflow.com/questions/27441230/why-isnt-my-act-window-with-views-definition-and-using-act-window-view-equival

So, you could call an action that specifies some python code which returns the list, graph, gantt, kanban, etc. views specified with the 'views' dictionary key.

Hope that helps!

I also just came across this:

I've never done it, but please try it and let me know if it works for you!

I also found the method with ir.actions.act_window.view and it all works with form,tree,kanban,graph but if I add list or custom_list to view_mode it tells me: ParseError: "Wrong value for ir.actions.act_window.view.view_mode: 'custom_list'" but in the normal ir.actions.act_window the view_mode custom_list works fine but not with a ref to a view_id.

Thx ... u put me on the right track ... just had to add custom_list to VIEW_TYPES in /openerp/addons/base/ir/ir_actions.py
