[TYPO3-mvc] Extbase and exceptions

[Dawid Pacholczyk]

Hello I`m creating my own functions with exception handling. If there is 
an error in some block of my function I use

throw new Exception("message");

The throw is for example in my repo

In controller the function that throws exceptions in in try{}catch{}

BUT

I can`t catch the exception. If the error occurs I get TYPO3 exception 
message. Cool but I don`t want to see this message. I want to make some 
magick in catch{} block. How can I do that ?
