ExtendedDataTable: refresh single rows???

[suprairc]

Hi there,
I'm using the 3.3.0 CR1 ExtendedDataTable and I have encountered difficulties when I'm trying to Rerender individual rows in the Datatable.

I'm in the following situation:
I have the ExtendedDataTable and I have buttons on the bottom of my page to switch rows: Next, Previous, Last, First. When I click on them I want the Datatable to set the new Selection.

This works, but the problem is that I have to reRender the whole Datatable to set the new Selection. What I want is that I reRender the old row and the new row and not the whole Datatable.

I tried Using:
datatable.getClientId(context) +NamingContainer.SEPARATOR_CHAR + "n" + NamingContainer.SEPARATOR_CHAR + numberOfRow;

But this didn't work, I get an error in my console: can't find component, and I think It's because the rows don't exist on the server side, so my application can't find the rows to reRender.

Does anyone knows what I can do to reRender only the appropriate rows, and not the whole Datatable?

Thanks in advance.

Hello,

Try to use ajaxKeys attribute. It should be bound to a set of row keys for selected rows. Get more info here: http://java.dzone.com/articles/an-introduction-to-jboss-richf?page=1,5

OK, I tried to use the ajaxKeys attribute, but still it reRenders the whole thing. When I change rows using the button it will fire my own implemented method gotoRow in the extendedDataTable, which sets the ajaxKeys to the old and new row.

I then reRender the dataTable using the clientId from the dataTable, but this still reRenders the whole grid, and not just those 2 rows...
