1) if my hashmap(contractorRecords) gets 14 records there are more calls to getRowCount. Why is that happening. when I move up and down the scroll bar then values change in the console.
2)I am using hashmap in which the key are the record Numbers. I have no idea how to pass the keys to the main file so that it can be selected my the client but at the same time should not be displayed in the table.
