Convenience function for fetching the current value of each field in the form. This is the same as calling
{@link Ext.form.Basic#getValues this.getForm().getValues()}.

@inheritdoc Ext.form.Basic#getValues
function(asString, dirtyOnly, includeEmptyText, useDataValues) {
        return this.getForm().getValues(asString, dirtyOnly, includeEmptyText, useDataValues);
    }
