Beta 3. The problem is that some classes get loaded in the main swf and
some classes get loaded into the child swf and sometimes the VM gets
screwed up in reconciling everything.
Let's see if I put the word "Roger" in here (and in the subject) if he
happens to see and can confirm.

Subject: [flexcoders] page change not work when loaded(FB2 beta2 +
ColdFusion)
hi flexcoders;
The idea is I have a "container" swf, a "list" swf and an "add" swf.
When "container" swf is running, it first loads the "list" swf and
displays some buttons like "add". The "list" swf displays data in
several pages and you can change the page with a horizontal slide. When
"add" button is clicked, the "add" swf is loaded and displayed with some
buttons like "cancel", "submit" and "clear". And in "add" swf, when
"cancel" button is clicked, the "container" swf should display the
"list"
swf with its current state.
It's really disturbing me because when "list" swf runs as a single swf,
page changing works ok, but when it's running as a loaded swf by
"container" swf, page changing gave me the following two errors:
TypeError: Error #1034: Type Coercion failed: cannot convert
mx.messaging.messages::[EMAIL PROTECTED] to
mx.messaging.messages.Message
TypeError: Error #1034: Type Coercion failed: cannot convert
mx.messaging.messages::[EMAIL PROTECTED] to
mx.messaging.messages.Message
I guess I must have missed something but I tried with no luck. And I
just couldn't figure out why the errors only occured when loaded.
Any help would be appreciated.
