PrimeFaces DataTable CellEdit get entity/object

Question

I have a datatable which displays various entities based on a List<>. When I select a cell for editing I want to be able to also get the entity somehow in order to update it.

Answer 1

One way would be to programmatically EL-evaluate the current .

Given a

you could get it as follows

public void onCellEdit(CellEditEvent event) {
    FacesContext context = FacesContext.getCurrentInstance();
    Entity entity = context.getApplication().evaluateExpressionGet(context, "#{entity}", Entity.class);
    // ...
}

Another way, if you're not interested in the CellEditEvent argument, would be to override the CellEditEvent argument altogether by passing the currently iterated entity as argument instead:

with

public void onCellEdit(Entity entity) {
    // ...
}

Please note that you cannot keep the CellEditEvent and pass additional arguments. This answer would otherwise obviously have been given.
