Dynamic SelectionCell

[Ousti Driss]

Hi everyone!!
I have a cell table which contains three rows.
I added a selection cell column,
the problem is the contents of this columns is static, I need something
similar, but instead of being static I can update it with the response I
get from my servlet
is such thing possible?
Thanks !!

Of course it is possible, just look at the CellTable in the GWT Showcase:

Instead of a DataProvider as in the example, you probably want an
AsyncDataProvider which gets the data from the server through your servlet.

Can you elaborate ?
I managed to update all the columns with the response I got from the
servlet, except the one with the selection cell,
this is how I instanciate a SelectionCell
Column<Record, String> categoryColumn = new Column<Record, String>(new
SelectionCell(list)) {
}
where list is a List<String>,
therefore all my rows have list as value in the categoryColumn ...

I misunderstood your question to mean that you just wanted to make data
dynamic in your table, which looks like you already are, except for the
SelectionCell.

Looks like SelectionCell can only get its list of available options in its
constructor, so what I would try is getting the updated list of options
from the server (or wherever you get them) before getting the new values to
display on the table, replace the SelectionCell with the new values in your
table, and then get the values to display on the table immediately after
(assuming you get a new list of options for the SelectionCell every time
you get a new list of values for the table).
