Hi,
the demo workplace's text tells about the background:
Code:
...
And, please note: the default behaviour of the grid is, that once a row was selected the next selection is not passed to the server side. You can override this default behaviour by using the attribute FIXGRID-RESELECTABLE. If you want your user to select different columns, one after the other, within the same grid, you need to swt FIXGRID-RESELECTABLE to "true".
...
The grid always a bit has the dilemma: do not send too many info in order to avoid roundtrips.
Regards! Björn
