[Seaside] Nested Editor Components - One More Time

You probably should give some details as to which Smalltalk, which version
of Seaside etc. I could not get the mcz package to load so I am going by
what I can glean from viewing the changes in your package. There are a bunch
of rendering methods that got added to the class side somehow that I think
is the cause of the failure to load. Try removing them and repackaging your

Usual usage for a report of items like the phone report is to put an Add
button somewhere other than on the row of the existing item (other wise how
would one be able to add the first phonenumber). The Add button should
"call" the phone editor: self call: PhoneEditor. The phone editor would
return a Phone object instead of true or false so the call then looks like
           p := self call: phoneEditor.
          p isNil ifFalse: [ phones add: p ].

And your phone editor should  answer: phone instead of true/false

The PhoneReport is a child of the Customer editor, so calling the
PhoneEditor in this manner should only replace the Phone report not the
Customer component. This way the Customer data does not "disappear". Why it
is not doing that I cannot tell since I cannot run the code.

Hope this helps
