I’m disappointed with the new version not including a new version of server behaviors with SQL transactions support. This is one of the functionalities that would be very useful since in behaviors with UPDATE or INSERT we can’t expect that all are going to be successful. If there’s an error, without transactions you can’t rollback the entire operation. I think that transaction support would be easy to include since I usually change the code generated by MX and it takes only a couple of lines for each behavior.
