add empty value to combobox ?

[dedoz]

how to add an empty selectable "value" to a Ext.form.field.ComboBox thats using a store ?
pretty much like adding an option like <option value="null">&nbsp;</option> to a regular select.

just add / insert it to the store that the combo is using and use an &nbsp; as for the field, that is defined as the displayField.

thats a bad solution i think, adding "false/weird" records to the store and then i let user edit add/remove records from the store or do sync.

anyone with a solution that doesnt need to insert records to the store ? or a user extension ? :d
