Is there any reason why used database.useTransaction method instead of database.useConnection while we call Database.insertAndGenerateKey(table, block)? Is it tested? Because, in my case, but log says everything is okey(printing effects count and generated key), transaction don't be committed.
Can anyone clarify situation. Is there bug or it's my wrong?
