Re: CellList row data - possible bug?
I think we should add CellList#setRowData(List value) that does not take a start index. Using that method would assume that the List of values was the complete list and would set the row count to the list size.

Thank you Chris and John. Yes, that was somewhat counterintuitive ;), but now I get the idea. Best regards! On 28 Paź, 15:46, Chris Conroy wrote: > setRowData deals with the visible display of data.

Re: CellList row data - possible bug?
setRowData(0, list_with_2_elements) "replaces" elements 0 and 1. Its designed this way so you can do incremental loading, or push updates of specific rows. If you want to hide the last three elements, you have to set the row count: CellList#setRowCount(2, true); Adding more data to the CellList automatically increases the row count. As Chris mentioned, using a ListDataProvider is an even better option. Any modifications you make to the underlying java.util.List (via ListDataProvider#getList()) will be reflected in the table.

Re: CellList row data - possible bug?
setRowData deals with the visible display of data. What you really want to do in this case is use a ListDataProvider. You can call setList on your ListDataProvider and it will handle the updating for you. Somewhat counter-intuitively, you add the display to the list provider--not the other way around. So... ListDataProvder provider = new ListDataProvider(); provider.addDataDisplay(myCellList); provider.setList(list_with_5_elements); provider.setList(list_with_2_elements); On Thu, Oct 28, 2010 at 6:07 AM, Rafi wrote: > Hi! > > Either I do not get the idea or there is a little bug in CellList. > > Calling: > setRowData(0, list_with_5_elements); > > Will show cell list with 5 elements. > > Then calling on the same CellList: > setRowData(0, list_with_2_elements); > > Will show cell list containing 5(!) elements.
