network-published shared variable, No overflow/underflow warning for Arrays ?!

Hallo,

 

Read about the Network-Shared Variable on the NI-site, now i´m having some questions about that statement.

 

Quote: http://www.ni.com/white-paper/4679/en  "Buffer Overflow/Underflow"
"You cannot use the second approach with shared variables used inside a time-critical loop if the data type is an array because the real-time FIFO-enabled shared variables do not support the Custom Control (cluster) data type if one of the elements of the cluster is an array."

 

In my vi, i´m checking the Error Code  -2220 , for an empty Shared Variable. If so, i´m switching to another case, in my Vi.


That was also shown so by NI in an example for my cRio Device.

 

 

But as i See, this approach doesn´t work. :S
