Hi Ben,

I had actually forgotten about that problem with nav elements. One 
solution is to just keep clearing the cache often enough when doing 
changes in the Back End. (Not very reliable)

Another solution (not actually tried for this purpose) would be to use 
the "clearCacheCmd" which I read about in the lastest tt_news 
manual (and have used successfully with tt_news).

When you make changes to any of the records of a page the cache 
for that page is cleared. By adding the following code to the TSconfig 
field of the page header will also allow you to clear the cache of other 
pages at the same time. So put this in all of the pages that are 
included in the navigation element (menu) and add the id of the page 
that has the navigation element in it.

TSconfig
=====
## clears cache for other pages when edited or cache cleared
TCEMAIN.clearCacheCmd = 21,152,202
=====
Note: "21,152,202" are just examples. Use a comma seperated list 
og pid values.

Of course this means lots of code in various TSconfig fields so it is 
not a good solution. I would not recommend this for a whole sitemap. 
Then it would probably be bettter to just set the page as non-cached.

Hope this helps
