Odd behavior with create constant and VISA GPIB Control REN

[ned]

Try this: place a case structure on a block diagram. Put a "VISA GPIB Control REN" node inside it. Right click on the "mode" terminal and choose "Create -> Constant." The constant appears on top of the case structure, rather than inside it. If you drag the constant away from the case structure, it appears to have a valid wire, but doesn't.
