the construction of my table follows this sun java tutorial: i've a custom model and also have two things tutorial refers: a combo inside table cells and also use TableSorter class in order to have sorting.
I use Jtable to display database data, and also use it to have updates, using combo's selected value; i get the selected line, then get the needed values from that row.
what i cant figure out is why i lose focus in selected row (and therefore i cant control my input to updates) when i first click table headers and only after that i select a certain value from a combo: the instant i click combo�s value, row loses focus! - so i'm unable to perform my update, since i ignore my row and its relevant associated data.
i'm using this method to get my row:

how can i turn this around?

at least i found out the reason of last error msg: when i select the cell, all is fine; but when i open combo and click one item, row loses selection and therefore the error msg
my problem is why does it loses selection
