In the Editor class, exists the function onEditComplete, with set the value to the column field. In this function has a check, if the field has a colon in the name, to complex field name, but the function used to fill the value is the "set" function, of the record, and to work as expected must be the "setPath" of ObjectHelper, this can be changed in the next release?
