When used in an EditorGrid (based upon the example "edit-grid.js"), Ext.form.Checkbox doesn't seem to work when rendered upon a dialog (BasicDialog or LayoutDialog).

I put some alerts down in Ext.form.Checkbox:etValue, getValue.

what actually happens, is that the editor immediately flips out of edit-mode as soon as one dbl-clicks the field (too fast to see, but visible when using alert() since processing stops)

on one double-click of a checkbox, console.log log shows:

>setValue()
>setValue()
>getValue()
>setValue()
>setValue()
