Plastic--Can a Void be run in test mode

[Larry Schultz]

I'm in the final stages of testing and I find running a void transaction returns the following error

3|2|16|(TESTMODE) The transaction cannot be found.|000000|P|0|||0.00|CC|void||||||||||||||||||||||||||1CA8E92FDC9DCC9CBE375ED0269108C4||||||||||||||||||||||||||||||

I had run the process payment just a moment before.

I guess my question is: Is this a problem in my coding or is this what to expect when testing agains the test account that comes with Plastic.

TIA,

Larry
