Rethrow-fault is unavailable to add

Has something changed in Oracle Integration 3 in regards to the "Rethrow Fault" action? I'm unable to add it into my integration.

1. It's available under actions to select.
2. But it has this big red circle when I try and add it somewhere.
3. It's also not available in the list when you click the '+' icon instead.

EDIT: It appears that it's unavailable underneath the SWITCH statement whilst in OIC2 it could be used there, hence the existence of the below. The purpose of it is to throw the integration entirely if it's an unhandled error.
