[Typo3-dev] BUG: Conditions processed twice

[Carlos Chiari (DE)]

Hi Kasper:

Using an user_function which depends on $GLOBAL['obj']->variable being set
to decide if a condition matches or doesn't, as the "Screen Resolution
Detection" extension does, will be tricky, as this variable could change as
the function is run multiple times.

Anyway, knowing the source, I will dig into it to find out how it works and
maybe a workaround.

Thanks, and best regards,

Carlos

I checked it out. In class.t3lib_tstemplate matching of conditions are done
multiple times it seems. This is no bug but a quite normal and valid flow.
Of course you could argue that caching of the results could be used.
Anyways, this is not the case and it is not a bug since noone promised you
that a condition could not be evaluated twice in the same run.

Whether or not this behaviour can easily be changed is not clear to me.
