Consider two possible tricks:
(1) Use an Iframe -- generate whatever dynamic content and place the iframe
in the lens. When the lens instantiates,
iframe generates a separate request and places HTML results in the
iframe. This is considered "cheating" in the
AJAX world because it's guaranteeably simple and reliable and there's
no chance of it breaking in some unexpected way , plus it won't
behave differently on every operating system, browser, browser version.
Where's the fun in that?
(2) Consider also using the lens ex:onshow callback

Although in my case, i was unable to get ex:onshow to work "portably"
and reliably on IE for my needs, which was to put my Xwiki integration
of the JWPlayer
<http://nielsmayer.com/xwiki/bin/view/Macros/JWPlayerJSPL_Test> flash
media player in a popup bubble. That's a somewhat unusual application
where SWFobject 2.2 attempts to portably run a flash player out of
javascript by replacing a given DIV in the document with the flash
player. One of the issues with lenses is that they strip out any ID's
from the lens-template, leaving only names or classes. I attempted to
use ex:onshow to programmatically find the correct div (named by
class) and then forcibly give it a name/id in order to get swfobject
2.2. to work. This worked fine on Safari&Firefox, but failed on IE due
to timing issues. It was all good in the end because it forced me to
do the right thing, which is to put the player in it's own viewpanel,
and now I just have to get it to appropruiately hide/display some
facets based on switching viewpanels:
