You probably guessed it but I'm voting for removing this feature. Opening of datasets and establishing database connections behind the back of the programmer is always a bad idea. The try open when loaded (streamed), even in the fixed version, has also the nasty side effect of not being deterministic. A programmer can't easily influence the loading order of components and a change in the order will change the behavior of the program. The fix in 22337 solves the exception but not the unpredictable behavior. If the link dataset and connection are loaded before the dblookup it will open the dataset, else it won't. So your program can start up with (some) dblookups pre-loaded or not. We shouldn't support users counting on unpredictable behavior.
