Hi, I've been trying to call the python method from the web client. The method is

action_invoice(self, cr, uid, ids, context=None):

In javascript, I call this method via

var model = new instance.web.Model("pos.order");

model.call("action_invoice", [], {context: new instance.web.CompoundContext()});

But it doesn't work. The error says that I lack one argument in the call. I think what I miss is the arguments "ids". From googling, it seems to be a list of record ids. What is it anyway ? Could you please tell me what is it and how to store that argument it in the javascript ?

Thank you very much
