Ted,

>OK I am stumped, there must be an easy way to convert an array/arraylist to an MM.net dataset/entity? In the .Net or MM.net framework?

You will probably have to loop through your ArrayList and create new entities from the values in each element. For example:
ArrayList list = new ArrayList();
for (int i = 0; i < list.Count; i++)
{
OrderEntity entity = MyBizObj.NewEntity();
// set the entity properties from the ArrayList values
}

Best Regards,
