Ok...I can reproduce it. The difference between Pharo 3.0 and 2.0 is likely that in 3.0 we have the new Opal compiler. If I debug your problem, it seems Opal is not able to even parse the method. It fails with a��SyntaxErrorNotification. Example:

Variable or expression expected -> renderContentOn: html
self wasShown
ifTrue: [ ^ self ].
self messageString
ifNotNil: [��
self messageType = 'error'
ifTrue: [��
html tbsAlert
beDanger;
with: [ html text: self messageString ] ].
self messageType = 'info'
ifTrue: [��
html tbsAlert
beInfo;
with: [ html text: self messageString ] ].
self messageType = 'success'
ifTrue: [��
html tbsAlert
beSuccess;
with: [ html text: self messageString ] ].
].
self wasShown: true

I do not get an error in the Seaside one-click experience 3.1 from seaside.st
pharo page which uses pharo 2.0

With a fresh 3.0 image and loading seaside 3.1 using the Gofer method - the
issue persists (i.e. I cannot save code from Seaside class browser and get
an error:
�� �� �� MessageNotUnderstood: receiver of "generateWithSource" is nil
�� �� �� Your request could not be completed. An exception occurred.)

and this is further broken in pharo 4.0 where the class browser does not
come up completely

can I get some help as I do not wish to revert to an older pharo version

regards
Sanjay
