Kristian,
Thanks! That will work just fine. I suspected performance was the driver
but was hoping that there was a way of selectively adding some script
includes to the top!

reason for adding js libraries at the end of the document:
https://issues.apache.org/jira/browse/TAPESTRY-2364
you could write an own Flash component that adds the js
libraries into the head section:
public class Flash() {
beginRender(MarkupWriter writer) {
Document d = writer.getDocument();
Element head = d.find("html/head");
head.element("script", ...);
}
}
i think you get the idea

Re: T5 5.0.13 Javascript rendering at end of document - questions regd
Filip,
That will not work because 1) the Flash player javascript is called
in-line to render the Flash player and 2) within the flash player
javascript, I've got some dynamic parameters being added. I can rework (2)
to make it a function parameter and put the dynamic nature in the inline
function call but that will still fail. Here is why:
<html>
<body>
HTML tags ....
<script> renderFlashPlayer(${myParam}) </script>
Other HTML tags ...
<script src="flashUtil.js"/>
<script src="flashPlayer.js"/>
</body>
</html>
So if renderFlashPlayer lives in flashPlayer.js, it will simply not work!
My
only alternative is to manually include flashUtil.js in the header and
inline flashPlayer.js. This is unnatural and against the grain. I suspect
that there are other similar scenarios.

Actually, you can just put the JavaScript in a .js file and then include
it with @IncludeJavaScriptLibrary. Then add a call to
RenderSupport#addScript in your page's afterRender handler that does the
setup you need.
For this and more, check

One more addition: When including the flash player in a page, the
recommended technique is to put inline javascript that renders the
flash
player where the javascript appears in the page. The javascript relies
on
an external javascript file being included. If I do an asset injection
of
the Flash javascript, it ends up at the bottom of the page and the
flash
player inline javascript fails. So it seems like one would need to
override this behavior. Otherwise I'd have to package up the inline
javascript as a method, inject that and then call it in place. But I'm
concerned with putting all the javascript for the flash in a Java file.
That is not a natural fit.
I have some questions regarding the decision to render Javascript at
the
end of the document:
1) What was the rationale/dirver for this?
2a) The upgrade notes say to use RenderSupport. Can anyone provide a
short description of how to use RenderSupport to inject a simple
javascript function?
2b) This implies that a lot of inline javascript will have to be moved
from .tml to .java classes. It seems this will reduce the
"naturalness"
of being able to use javascript normally.
