Body
I am new to JBoss Seam. I wanted to test some stuff on Eclipse so I created a new project and attached it to a mysql db. I then created a seam entity that I wanted to use to connect to my db. This seam entity created a .xhtml file and then a .java file. The problem am having now is that when I run the file to see whether I can persist in the db, I get the following error <pre><code>Exception during request processing: Caused by javax.servlet.ServletException with message: "/person.xhtml @21,67 value="#{personHome.instance.name}": Target Unreachable, identifier 'personHome' resolved to null"

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.
