I am listing the code below

My questions are

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.

I don't understand your problem, but it would be easyer if you used an arraylist instead of a hashtable.

How did ypu finally work around this issue of displaying the hashmap in a JTable. I am facing a similar issue currently and i came across your post here.

Your help would be much appreciated.

Hi Uzma,

(First Question)

Could you explain further I do not understand your question. It sounds like a Swing rendering issue but I am not sure.

(Second Question)

You can have the TableModel store, but not display, the column numbers as part of the data model.
