Grid v8 nested properties

Hi,

while experimenting with the new Grid (v8) API, I wondered how to set a nested property on a (databound) Column (via DataProvider).
In v7 Grid it was possible via e.g. AbstractBeanContainer#addNestedContainerProperty

Anybody got ideas?

Thank you, I'm still surprised by Java 8 features :)

Enjoy! ;)

Alejandro Duarte: Yes, use a ValueProvider so you can show whatever you want. For example:

grid.addColumn(user -> user.getAddress().getCountry().getName());

Thanks a lot Alejandro,  I can sleep in peace...

Haha cool! And at least you can. I can't today. Not much. Have to write a book. About Vaadin :) Deadlines! Anyway, sleep well!

But what to do if you want to do something with a column that refers to a nested property?

The only way I found is to store the column in a variable. But that is not very elegant, is it?

grid.addColumn(user -> user.getAddress().getCountry().getName());

Hi Alejandro.

When the address of any user in the ListDataProvider is null, I get a NullPointerException. How do you treat this exception?
 

I avoid throwing the exception using an if statement or ? operator: user -> user.getAddress() == null ? "" : user.getAddress().getCountry().getName().
