I'm fairly new to Hibernate and just noticed something odd in our logs. After doing a retrieve of the StructuredDeal object and consequently the TradeReviewApproval objects, then displaying the data on a JSP, there is also extra unecessary update of the StructuredDeal and all the TradeReviewApprovals

Any ideas what could be causing this?
