[TYPO3-dev] Javascript error on Clickmenu

[J. Lingott]

Hello,

currently encountering a weird error when clicking on Clickmenu items. 
The error is 'docRef is undefined'. Don't really have a clue where it 
derives from as docRef is actually defined when clicking on the item. 
All other variables referenced on that JS snippet (top, Clickmenu) are 
defined as well, but it keeps spitting that error. Any assistance would 
be appreciated.

Cheers
