Here is a compiler bug, which can make your life a nightmare when you are not aware of it. Maybe, it is not very popular situation, but sometimes it is enough to spens a hour fighting with the code like this, where error is present, but no compiler error is given:

...

case newMessageByUser:

 var html:String = "11";

 html = '<h2>@<a href="'+cnf.juickBaseURL+uname+'">'+uname+'</a>:</h2> '+

 '<p class="replyQuote">'+juick+'</p>'+

 '<p><a href="event:LinkEventReplyTo:'+mid+'">Reply to #'+mid+'</a>, ' +

 'Web: <a href="'+murl+'">'+murl'</a></p>';

 trace("html=" + html");

 break;

...

The safe technique to discover such errors is to wrap the whole "case: " block content in the curly braces, which will raise compiler error to inform you where your error is:

...

case newMessageByUser:

{

 var html:String = "11";

 html = '<h2>@<a href="'+cnf.juickBaseURL+uname+'">'+uname+'</a>:</h2> '+

 '<p class="replyQuote">'+juick+'</p>'+

 '<p><a href="event:LinkEventReplyTo:'+mid+'">Reply to #'+mid+'</a>, ' +

 'Web: <a href="'+murl+'">'+murl'</a></p>';

 trace("html=" + html");

 break;

}

...

Have fun :)
