Exception problem during event

Hi!

I have problem with catching exception during event...

I have subscribed event on method update() in CustTable...

And i have this part of code which have to handel it...

try
{
    breakpoint;
    throw Exception::Error;
}
catch
{
    info("Exception");
}

When i update record in CustTable event start but when Exception occured it doesn't jump to catch section but to method leaveRecord in CustTable...

Why does it happen ??
