I just discovered that it’s impossible to make a dynamic schema with the new “Module into Module” schema. In fact, each page is built statically, no matter if there’re dynamic code included among the templates.
I love to do examples to make better understand what I say:
Let’s say there’re 1 entries and 1 comment.
Previous MT versions: “Main Index” includes “Recententries” “Indidivual Entry” includes “Recententries” Recententries is is a snippet-code in MT language, rebuilt each time and outputting to “Recententries.shtml”.
One entry more is published, and 1 comment done. Result: dynamic code is executed. “Main Index” shows now 2 entries, 2 comments. As all entries that show 2 entries, 2 comments
MT 4.x: “Template” includes “other-Template” that includes “Recent_entries”
Result: dynamic code is NOT executed. “Main Index” shows 2 entries, 1 comments. All entries show 1 entries, 1 comments.
In other words, only the page interested by a rebuild show the changes. All other pages remains unchanged because they not include the Recent_entries.shtml file.
The only way with the new MT having own website updated, is to rebuild whole website each time! (In my blog, it means wait 1 hour each time I post an entry. )
This is amazing. Not, it’s terrific. I hope I’m missing something!

You are missing something. I explained this in the previous post you did about this issue, and how to get around it. I explained how to do this with PHP, and why using <mt:Include> will not meet your needs if what you said is true about it not generating the proper SHTML or PHP include statements.
No, the fact is that I cannot explain properly what happen, and you don't understand, in my sensation. The shtml file do CONTAINS the 2 entries and the 2 comments correctly! Instead, the index, the entries, etc etc, are built statically: they keep on reporting 1 entries and 1 comment until I rebuild them!
I apologize. Now I will graphical a little UML diagram to render what I want to say... :)
The only reason why they would report that is if they aren't properly loading your SHTML file, such as would likely be the case if <mt:Include> is not generating the right statements for loading the SHTML file.
