  - by Dieter Gantz

  In this JDO, why is .class needed here? Query averageSalaryQuery = pm.newQuery(Employee.class); I would prefer to write this more concise syntax if possible? Query averageSalaryQuery = pm.newQuery(Employee);

Thanks, Don

• How do I run jQuery form validation by class?

  - by joshcomley

Take this example: $("#myform").validate({ rules: { field: { required: true, date: true } } }); Where field it is expecting the name of the particular input.

• Hibernate cascade delete on a bag

  - by littlecharva

  Howdy, Having built most of my DAL using NHibernate, I've now discovered that the SQL Server's Cascade On Delete rules also need to be taken into account in my HBM files too. I've been using bags for all my collections, but there doesn't seem to be a way to add a cascade="delete" attribute to a bag. I can change all my bags to sets, but that appears to mean I have changing all my IList<s on my models to PersistentGenericSet<s, which I don't really fancy doing. Any advice? Anthony

• Extension Methods - IsNull and IsNotNull, good or bad use?

  - by Jaimal Chohan

  I like readability. So, I came up with an extension mothod a few minutes ago for the (x =! null) type syntax, called IsNotNull. Inversly, I also created a IsNull extension method, thus if(x == null) becomes if(x.IsNull()) and if(x != null) becomes if(x.IsNotNull()) However, I'm worried I might be abusing extension methods. Do you think that this is bad use of Extenion methods?
