entitymanager flushes on ajax request
Hi,
I am trying to do some datetime calculations on the serverside with the help of a4j support tag. The problem is whenever I call the calculation function entitymanager tries to flush the data before executing method. And when the method is executed all the values are empty. Any idea what is going wrong here?
