reentrant / invariant VIs how to use...

Hello,

I have a problem to run a vi reentrant (invariant). I set the vi properties to reentrant and tried out two ways to start the vi. The vi is intended to open a new little window showing a device name and retrieving a measurement value for that device, thats all. I hand over a cluster including the attributes (like device name, connection id,...)

First "call vi per reference":

That does not work because the vi does not start immediately. A window is opened but the vi does not run. Than it is possible to start the vi through the vi run button.

Second "invoke node":

The "invoke node" works for one device the way i need it. But when a hand out other parameters for another device no second window is opened.

Hope someone can give me some hints.

Big THX

Attachement: The expand vi is my reentrant vi.
