nice tutorial, thanks ! For me it's the best tutorial in this technology sector, very amazing for getting in, thanks !
But some question: I added (for getting experience) an amount field in the contact entity (BigDecimal), but can't render it in the grid with new DecimalFormat("$ #, ##0.00")));
what do i wrong ? Thanks !

where exactly was this info about the library reload?

Something you missed with this one, for the new company column we added. There is no sorting functionality like there is for all of the other columns. Quick fix for everyone is after the .setHeader("Company") insert .setSortable(true); So the entire function would be:

grid.addColumn(contact -> {
Company company = contact.getCompany();
return company == null ? "-" : company.getName();

What i have actualy did was after implementing the one which shown on this video, i had created a tab while switching to employee it will show employee details and while awitching to company in tab it shows company details.

Iam facing an nullpointer exception while switching the company tab it says
CompanyService.findAll() is nulk do any one know what might be the issue

I simply don't understand why only Vaadin is worried with allowing Java developers to be able to make fullstack development in such a clean and simple way. This is like Swing for the 2010/20's+

Hi! How do I create a pagination in vaadin with datagrid? What should I add to the code?

[barney]

In grid.setColumns("firstName", "lastName", "email", "status"); can we somehow use the entity's fields to link it? I'm asking because if we changed the entity this would break easily.

i 50% when i run "build application" i get an Error: "Could not navigate to ''
Reason: Couldn't find route for ''
Available routes:
This detailed message is only shown when running in development mode." 
is there any solution for this?

Why muss we remove the key "company" first?

I mean why the following implementation does not work
grid.setColumns("firstName", "lastName", "email", "status");

it shows the error "...The column with key 'company' is not part of this Grid"
