Thanks very much for this pointer. <br><br>It works if I do:<br> (((s jQuery html: [ :r | self renderTweetsOn: r ]) hide) prependTo: (s jQuery id: #tweets)) slideDown: 'slow'<br><br>if I leave the () out around hide, prependTo: , slideDown: then smalltalk says to me that prependTo: slideDown: message does not exist...<br>

Hi Bart,<br>
<br>
The #prependTo: message is sent to 's' in the cascade. I think you mean this:<br>
<br>
html jQuery ajax script: [ :s | s << ((((s jQuery html: [ :r | self renderTweetsOn: r ]) hide prependTo: (s jQuery id: #tweets)) slideDown: 'slow')];<br>
<br>
also watch out with the following pattern:<br>
<br>
s << html jQuery keyword: #something<br>
<br>
I have gotten burned by "forgetting" that binary messages are evaluated before keyword messages. The correct form is:<br>
<br>
s << (html jQuery keyword: #something)<br>
<br>
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 :-).<br>
<br>
cheers<br>
Johan<br>
