Magritte examples in seaside/examples/examplebrowser

Ch Lamprecht
Hello,

trying to browse the Magritte examples in examplebrowser I found the following
issues:
One is with
WAComponent class >>
     headerForExampleBrowser
         ^self name = self description
                ifTrue: [ self name ]
                ifFalse: [ self description , ' (' , self name , ')' ]

The 'Comma' op is defined in MADescription and #, tries to send #asContainer to
the following ByteStrings. An DNU Error is thrown.


Another is:

MAExampleEditor instancevariable 'description' is supposed to hold a Collection
- at least it is used that way e.g.:

MADescriptionEditor>>
buildReport
        ^ (MAReport rows: self description
            description: MAElementDescription description)

however it is initialized with:

defaultDescription
        ^MAContainer new.

I changed
MAExampleEditor>>
description
        ^ description ifNil: [
            description := Array with: self defaultDescription ]

(adding the Array constructor) and that works. I don't know if it breaks other
things though...
Thanks for any suggestions and hints.

Cheers, Christoph

Oh yes, now I see: That breaks the edit/preview views -

I am unable to reproduce? How did you trigger this DNU? What is the  
stack trace?

MAContainer is like a collection of descripiton. What breaks with the  
current code? Why do you need to change it?

Cheers,
Lukas

Starting with Magritte-Seaside 248
(MAReport demo was dropped in the meantime :251 ??)
opening http://localhost:8080/seaside/examples/examplebrowser

First needs fixes in MADescriptionEditor>>buildReport to open without an error
  MADescriptionEditor>>buildReport

      ^ (MAReport rows: self description children "added children here"

             description: MAElementDescription description)

more fixes changing 'report refresh'  in add/edit/remove/Description

MADescriptionEditor example works in latest version of Magritte-Seaside (251) !



Then choosing MAReport from the dropdown list gives me:


Stack Trace

    1.

       thisContext
           ByteString(Object)>>doesNotUnderstand: #asContainer
       self
           ' ('
       aMessage
           asContainer

    2.

       thisContext
           MAPriorityContainer(MADescription)>>,
       self
           a MAPriorityContainer label: 'Report' comment: nil
       aDescription
           ' ('

    3.

       thisContext
           MAReport class(WAComponent class)>>headerForExampleBrowser
       self
           MAReport

    4.

       thisContext
           WAExampleBrowser>>renderComponentOn:
       self
           a WAExampleBrowser
       html
           a WARenderCanvas

    5.

       thisContext
           WAExampleBrowser>>renderContentOn:
       self
           a WAExampleBrowser
       html
           a WARenderCanvas

Please use with Magritte-Model-lr.301 and Magritte-Seaside-lr.251.

Is the dropped needed for the tutorial?

Hi,

no, it is not. I already switched to 251 and thought I posted that yesterday,
but I must have made a mistake and the post didn't get through to the list.

Thank you, Christoph
