[FLOW3-general] Get errors from forms

[Dawid Pacholczyk]

Hi List,
  I`m wondering how can I receive the errors from form while creating 
new record in db ?

For example in my model I have adnotation like this one:

  @validate Text, StringLength(minimum = 3, maximum = 80)

When I type something shorter I get:

An error occurred while trying to call 
Test\Core\Controller\UserController->createAction()

How can I catch the error ? I was looking something like try {} catch 
but it didn`t help :(

Best regards,
Dawid Pacholczyk
