Backspace not working properly when apply keyPressFilter

[lau.pping]

Hi,
When apply keyPressFilter in a textitem which has defaultValue, pressing back space key won't work when there is one last character left. The code below modified from http://www.smartclient.com/#formFilters to illustrate the problem.

isc.DynamicForm.create({
    fields: [
        {name: "name",
         title: "Name",
         type: "text",
         hint: "Mapped to uppercase",
         width: 200,
         characterCasing: "upper"
        },
        {name: "commission",
         title: "Commission",
         type: "text",
        defaultValue: 800,
         hint: "Numeric only [0-9.]",
         width: 100,
         keyPressFilter: "[0-9.]"
        }
    ]
});
