Description of problem:

There are several issues with the Seam2.3 seamdiscs example:

1. expanding the "+" on Bob Dylan will display a message "The form component needs to have a UIForm in its ancestry. Suggestion: enclose the necessary components within <h:form>"

2. clicking on Bob Dylan will open an error page with

/artist.xhtml @23,68 value="#{artist.bandMembers}": The class 'org.jboss.seam.example.seamdiscs.model.Artist' does not have the property 'bandMembers'.

3. Some empty edit box is displayed in the artist edit page even when logged out. When logged-in, there is also an additional empty edit box in addition to the edit box with the artist name.

4. Pink Floyd members are listed as Band Members in both Pink Floyd and Fairport Convention on the artists page:

(but they are correct in the database, so the nested rich:list in the tr:table  doesn't work properly)
