    1. COWhat if externalContext is null? Does something need to be configured so the client is using a session(like telling it to store a cookie)?

    2. COIt's never null. And no, the session is basically already backed by a cookie. In the very rare case when the client has cookies disabled (which you **cannot** enable from the server side on), then JSF will automatically take care about URL rewriting with `jsessionid` (only when you use `<h:outputLink>`, `<h:form>` and so on instead of plain HTML `<a>`, `<form>`, etc).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
