[TYPO3-dev] TYPO3 6.2

[Flo Rian]

Hi everyone, 

we just upgraded our TYPO3 version to 6.2. We developed an extension for managing the videos of our website and now when we try to safe a new video an error occurs with the message:
not a correct info array of constructor dependencies was passed! 


Another confusing thing is this. It occured In the Log but I don't know in which context: 
Core: Error handler (BE): PHP Warning: htmlspecialchars() expects parameter 1 to be string, array given in /typo3/sysext/fluid/Classes/Core/ViewHelper/TagBuilder.php line 174

The extension works great on TYPO3 6.17 so we are a little confused at the moment about what is causing the problems...

Thanks for your help!
