[Joachim Streit]

Hi list,
typo3 4.0 rc2 TV 0.7.0

TVPageModule ->Advanced Options -> klick "show outline"
give to me this error:
Fatal error: Call to undefined function: cleanflexformxml() in 
/home/httpd/vhosts/typo3delta.internetservice-dudenhofen.de/httpdocs/typo/typo3conf/ext/templavoila/mod1/index.php 
on line 1084
no Content is showing nothingt do be done here.

I just commenting out this line to get back to normal state.
then I see a list with my contentelements and the button "clean XML of 
all dirty elements above!"
again: "Fatal error: Call to undefined function: cleanflexformxml() in ..."

waht could be done?

by the way Thanks for this great solution TV!
