I found this wonderfull plugin: http://dev.s-cubism.com/plugin_multiselect_widget which looks awesome for the things I wonna do. But I don't get ist to work with a field which has a list reference table I want the field to be either empty of filled with an unlimeted amount of entries. So I had no required field at all: Field('Fruit','list:reference Fruits'), so I tried the following: from plugin_multiselect_widget import ( hmultiselect_widget, vmultiselect_widget, rhmultiselect_widget, rvmultiselect_widget, ) ... db.Cocktail.Fruit.requires=IS_EMPTY_OR(IS_IN_DB(db,'Fruits.id','Fruits.Name' ,multiple=True)) db.Cocktail.Fruit.widget = hmultiselect_widget which gave me the multiselect widget but When I mark a fruit and click on the register button nothing happens.
