Question

I want to make my tables ignore letter case when sorting, so I found this link, but I can’t figure out where I can actually make the table use the new ItemSorter.

Answer 1

You need to add the ItemSorter to the container used by the table; two container types expose #setItemSorter – IndexedContainer and AbstractBeanContainer. The default container for a Vaadin table is an IndexedContainer.

The following snippet should add an ItemSorter to a table.

Container container = table.getContainerDataSource();      
  if (container instanceof IndexedContainer) {
    ((IndexedContainer) container).setItemSorter(itemSorter);
  } else if (container instanceof AbstractBeanContainer){
    ((AbstractBeanContainer) container).setItemSorter(itemSorter);
  }
