Flexform: Default values are not immediately saved when creating a container

[stephangrass]

I have the following Flexform:

                    <specialLayout>
                        <TCEforms>
                            <label>Spezielle Layouts</label>
                            <config>
                                <type>select</type>
                                <renderType>selectSingle</renderType>
                                <items type="array">
                                    <numIndex index='0' type='array'>
                                        <numIndex index='0'>Standard</numIndex>
                                        <numIndex index='1'>default</numIndex>
                                    </numIndex>
                                    <numIndex index='1' type='array'>
                                        <numIndex index='0'>2 Spalter, rechts Contextspalte</numIndex>
                                        <numIndex index='1'>2col-typ2</numIndex>
                                    </numIndex>
                                    <numIndex index='2' type='array'>
                                        <numIndex index='0'>2 Spalter mit Headernavigation, rechts Contextspalte</numIndex>
                                        <numIndex index='1'>2col-typ1</numIndex>
                                    </numIndex>
                                </items>
                                <size>1</size>
                                <minitems>1</minitems>
                                <maxitems>1</maxitems>
                                <default>2col-typ2</default>
                            </config>
                        </TCEforms>
                    </specialLayout>

It is desired that the second entry be activated immediately upon creating the element. However, the set default value is only activated upon re-saving the container.
