When running JBoss BPM Suite with a Sybase database instance, querying a process variable that has a null value returns a single space character (" ") instead of null. This is a limitation of the Sybase database, and there is currently no workaround.

while I see your point that it might be confusing I don't see anyway to solve it. Mainly because there could be the opposite situation you described - a process variable is single space value and then it is not possible to recognize if this is null or not. I am afraid that this is (yet another) limitation of sybase that does return weird values. Since we do not have control over data access (done via jpa) meaning we cannot decide if shall deal with single space somehow or not. I opt at closing this as won't fix, thoughts? I think it can be closed then. However, we should add a note about this strange behavior of Sybase to our documentation. |
