28531	MultipleChoiceField / CheckboxSelectMultiple values linked to a CharField not restored on bound model forms	Benjamin	nobody	"I'm building the 'edit' page of my form. This page is supposed to show form with the data that was saved, so the form is pre populated with saved data. It works fine for most if the fields, but I have a problem with 'MultipleChoiceField' / 'CheckboxSelectMultiple' values that don't get restored. So instead of having the corresponding checkboxes checked with data from the saved form, they are all unchecked. This also affects 'SelectMultiple'
Could this be a bug ?
