[Typo3] 'tslib_pibase' in the BE

[Christian Prokopp]

Hi Folks,

I am writing an extension which covers a frontend plugin and backend 
module. I nearly finished the frontend. Now I would like to use the 
same/similar listing, browsing and searching I have in the frontend in 
the backend module. After running in some trouble I found a post 
somewhere from Kasper explaining that the 'tslib_pibase' can not be used 
in the backend and as my frontend class extends it I have a problem. I 
obviously tried moving parts of the code in a shared 'tslib_pibase' 
independent class. Works fine until I hit the parts that use...guess 
'tslib_pibase'.

Is there a similar class for the backend I can use or any other smart 
way that saves me from rewriting parts of the 'tslib_pibase' functionality?

Cheers,
Christian
