[TYPO3-project-formidable] Template Engine: Bug when using isLoggedIn().isFalse() twice

[Hauke Hain]

Hi,

I am not quite sure why my templates does not work with formidable without 
changing the pattern.

If I do not change it to $sPattern = '/\<\!\-\-.*(\#\#\#(.+)\ 
\bperimeter\b\#\#\#).*begin\-\-\>([^\\1.]*)\<\!\-\-.*\\1.*end\-\-\>/';
I do not get anything displayed.

However, can you repeat the Bug? I think the whole thing would work with 
replace instead of using regular expressions, as TYPO3 uses it.

If it is ok, you may change the $pattern to my version. It is a bit more 
specific and the groups are different. And it works for me only.
On the other hand: Can you imagine why this happens to me? Perhaps you see 
something I don't (within the other posts in this thread).

Thank you in advance.

Kind regards,
Hauke
