| Unable to retrieve index in model from selection [message #1219013] |

Hello,
I've implemented a NatTable with GroupBy, Filter and Sorting capabilities. All work greats. But when I register on RowSelectionEvents (with a RowSelectionProvider) I'm unable to retrieve the position of the selection in my underlying model from the selected row index.
Example :
With no filter applied, if I select the row 0, it corresponds to the item 0 in my model.
But if I activate some filter and I select the row 0, the corresponding item in my model is not 0 but, maybe, the item 149.
So I'm trying to convert the position 0 in my selection layer to the correct index in my model.
I've tried :
LayerUtil.convertRowPosition(selectionLayer, rowPosition, bodyDataLayer)
selectionLayer.localToUnderlyingRowPosition(rowPosition) 
Regards,
Alain

Thank you for your reply. I didn't realize that the NatTable index was the FilterList index.
But in fact, the problem was that the filterList.get(index) returned me the wrong object because I worked on an outdated FilterList: I'm in an Eclipse editor and the model must be refreshed at each time the source file is modified. My update strategy was not a good one for the FilterList and the NatTable therefore worked on an outdated list. I resolved that by refreshing directly the underlying EventList which transmits properly the update to the SortedList and then to the FilterList.
