what do I rerender when setting ajaxKeys

[suprairc]

What do I have to reRender when I set the ajaxKeys? I tried all the clientIds of the columns and I tried reRendering the whole datatable...

When I set the reRender to the whole table, it rerenders the whole table. When I set all the column clientId's as reRender, nothing will be rerendered.

My situation:
ScrollableDataTable with navigation buttons which set the selection of the dataTable. When I click on one of the buttons, I dont want it to reRender the whole table, I just want to set the selection to the new Row and reRender the old row and reRender the new Row.

I just can't get it to work, I hope you guys can help. Thx in advance

define the column children directly. a4j:repeat page at richfaces-demo contains the example.

Do I set the columnChildren as reRender on the button, or on the table?

OK I think it works....but there is one problem.

What I really want to do is set the selection server sided and reRender only the selection, I want to set the selection without rerendering the whole thing.

Is this possible?

not sure that quite understand you.. ajaxKeys should works just as you described.

No it rerenders the rows correctly, but it doesnt set the selection... I want the new selected row to be highlighted. This does not happen.

look.. you have two opportunities there. update the cells (current state) - updates the td's content. And update the table(updates all the table) Using first one - you will not be able to set selection because only td's content updated.

Can this be implemented?

reRendering the selection only???

[ilya_shaikovsky]

currently only table rendering. In theory you could use scriptVar in order to access scrollableTable object on the client. Then you could explore our selectionManager client side implementation to check for the function which can be used to select rows - but this API still not public.
