Doesn't matter where the method is, your state machine clearly has
blocks stored as instance variables and you're trying to save the state
machine as part of the Order; SandstoneDb doesn't support saving blocks.
I'd try what Dennis Suggested and store message sends rather than blocks
for the guarded method, then it might save fine.  Inspect the state
machine, any use of blocks has to be removed/changed to message sends in
order for it to be persistable by SandstoneDb.
