[TYPO3] typolinks don't work when realurl is on

[Paul V]

Hi,

Having a major nightmare.  Trying to generate a print link and a couple of 
similar functions but stopped at first base because I cannot get a typolink 
to generate a value at all when RealURL is running.  The following TS is 
mapped in TemplaVoila to an href attribute on my template (I have also tried 
mapping to the container and changing the TS to generate the entire link)

lib.textOnlyURL = TEXT
lib.textOnlyURL .typolink {
returnLast = url
parameter.data = field:uid
useCacheHash = 1
}
[globalVar = GP:print > 0]
lib.textOnlyURL .typolink.additionalParams = &print=1
[global]

There is no output for this at all.  If I disable RealURL, it works and I 
get the standard index.php?= ... however, so I'm pretty sure the (very 
simple) TS is not causing the problem.  Also, in the same TS Setup I use 
typolink in a tmenu (for example) and it works fine.

My RealURL TS config:

config.simulateStaticDocuments = 0
config.baseURL = http://localhost/
config.tx_realurl_enable = 1

RealURL works fine otherwise.

Can anyone think what the problem might be?  Using Typo3v4, with Realurl 
1.1; TemplaVoila site.

Many thanks...

Paul
