Invalid LV Queue Ref in TestStand

Hi,

having trouble storing LabVIEW queue refs in TestStand: I'm trying to have an asynchronous LabVIEW process running in parallel to the regular test sequence. Communication with the async process takes places using a LV queue.

So what I do:

1.) Call a VI that sets up the queues and returns the Q refs

2.) Store the Q refs in Numeric variable within TestStand

so far, it seems to work. When stepping into the VI and probing the references, the numeric values correspond to those TestStand shows in the local variables shown during the execution

3.) Call another VI that checks the queues for sanity first of all (and fails: Get Queue Status primitive returns Error 1)

when probing this VI, the numeric representation of the queue refs seems to be ok.

So... TestStand is only used for storing the refs which should be ok according to the manual.

Any ideas?

Cheers

Oli
