How to use OmniFaces Ajax.updateColumn() or Ajax.updateRow() via p:ajax

Question

I am attempting to use the Ajax.updateColumn() method of the OmniFaces 1.3 (SNAPSHOT) Ajax utility. More specifically, I want to replace the use p:ajax update=\":pageContentPane

The key point is that you've got to have a handle to the UIData component somehow so that you can pass it to Ajax#updateColumn(). In your particular case, easiest way would be to get it by event.getComponent() with help of Components#getClosestParent().

UIData tripDatesDataTable = Components.getClosestParent(event.getComponent(), UIData.class);
// ...
Ajax.updateColumn(tripDatesDataTable, 1);

Note that you can also just get the row number this way without the need to break down the client ID.

int rowNumber = tripDatesDataTable.getRowIndex();
