I added 'attribute_1' to the MYSQL index (unique) to get, among others, a faster workflow (LS 2.05). The comfort update to 2.06 did not work, thats why I had to update by my own.
After update by my own (LS 2.06) I get the MySQL error: 'key specification without a key length' and the ATTRIBUTE_1 is mentioned too.
Info about this error message:

Did I make a mistake during the update or is their a problem with LS 2.06 and using of indexes in MYSQL?
