A copied component configuration doesn't work

Hi people,

I want do conform an application configuration in NWBC.

Therefore I copied the application configuration and the component configuration into Z-namespace and assigned the Z-component configuration

to the Z-application configuration.

I removed some not demanded UIBB in setting them not visible and my application configuration works.

There is one UIBB, I only want to remove a field. Therefore  I copied the component configuration of this UIBB into Z-namespace and removed the field and in the Z-component configuration I replaced the orgin configuration of this UIBB with this copied configuration. But in my application this UIBB doesn't work i.e. the fields are empty. They are also empty, when I only use the copied configuration without any changes.

Does somebody have got an idea, how I can solve this problem?

Thanks

Barbara
