[Seaside] Seaside: Jquery cascade messages

[Johan Brichau]

Hi Bart,

The #prependTo: message is sent to 's' in the cascade. I think you mean this:

html jQuery ajax script: [ :s | s << ((((s jQuery html:  [ :r | self renderTweetsOn: r ]) hide prependTo: (s jQuery id: #tweets)) slideDown: 'slow')];

also watch out with the following pattern:

s << html jQuery keyword: #something

I have gotten burned by "forgetting" that binary messages are evaluated before keyword messages. The correct form is:

s << (html jQuery keyword: #something)

The strange thing is that it often works without the parentheses, but might go completely wrong when you concatenate the scripts (been there, done that :-).

cheers
Johan
