JTable, fireTableDataChanged, selection

[Nosnos]

I use fireTableDataChanged to notify my Jtable to update, but when my JTable
updated, the previous selected rows (could be multiple) are lost ...

I want to know how to do to keep these selections when refreshing JTable by
this way ?

thx a lot

The fireDataChanged event implies that the data in all the rows of a
JTable could have changed, and rows could have got deleted/added, so it
seems a very reasonable thing to forget the selection status. Otherwise
you could get into situations where the selectionModel is trying to keep
a non-existent row selected.

In case you want to implement this, you need to first remember the
selectionStatus, mutate the data in the table, fire the events and
reselect the rows programmatically if they are still relevant.
