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
It is sorta covered in the JavaRanch Style Guide.
