Flatten / Unflatten to String: Losing Variant Data (Example Provided)

[Wiredup]

This is a simple one (I hope). When I take a cluster (which has a variant array as an element), I loose the variant data in the flatten/unflatten process. The simple panel and diagram are below. Where did the variant data go?

Seems to work fine for me in LV 7.0.

Can you upload an actual VI?

I think I may have found the issue. The problem VI is attached ("test1.vi"). The variants in this example are actually Database Variants. If I use the database type information to convert these variants to a normal variant, then the flatten to/from string works properly.

Please see the attached "DB Variant to FlatString.vi" that fixes the problem.  I'm learning all the time - just very slowly!

Yes, OLE variants are a problem. See here for some more examples. I think this may have been resolved in LV 8.x, but I'm not sure.
