I'm trying to understand what lead to this problem, but I really don't know
where to look for...
I'm using symfony-standard on master, and capifony to deploy.

The problems shows up only when I'm using capifony, not on local machine,
with the assetic:dump command.

This is the really strange command that I got on capifony:

--> Updating code base with rsync_with_remote_cache strategy
--> Creating cache directory...........................✔
--> Creating symlinks for shared directories...........✔
--> Creating symlinks for shared files.................✔
--> Normalizing asset timestamps.......................✔
--> Downloading Composer...............................✔
--> Updating Composer dependencies.....................✔
--> Downloading Composer...............................✔
--> Dumping an optimized autoloader....................✔
--> Building bootstrap file............................✔
--> Installing bundle's assets.........................✔
--> Warming up cache...................................✔
--> Dumping all assets to the filesystem...............✘

the same command that fails with capifony called locally works:

php app/console assetic:dump --env=prod --no-debug
Dumping all prod assets.
Debug mode is off.

tried with cap -d deploy and by viewing log files on the remote server. No
clues.

I really don't know where that "Class Vivacom\CargoBundle\Entity\string
does not exist" comes from.
The capifony recipe worked perfectly since 6 days ago, since than I didn't
make any deploy.
Today the problem shows up...

Any idea about what this could be? Or what can I do to debug this?

I managed to reproduce the problem locally!
It's a cache problem, that occur only the first time after clearing the
cache....for example

./app/console --env=prod cache:clear
./app/console --env=prod --no-debug assetic:dump ERROR
./app/console --env=prod --no-debug assetic:dump OK

even manually:
rm -rf app/cache/*
./app/console --env=prod --no-debug assetic:dump ERROR
./app/console --env=prod --no-debug assetic:dump OK

and also:
rm -rf app/cache/*
./app/console --env=prod cache:warmup
./app/console --env=prod --no-debug assetic:dump ERROR
./app/console --env=prod --no-debug assetic:dump OK

Any idea? This is really strange....

another weird behavior with the --no-debug option

rm -rf app/cache/*
./app/console --env=prod --no-debug assetic:dump ERROR
[ReflectionException]                                  
  Class Vivacom\CargoBundle\Entity\string does not exist  

rm -rf app/cache/*
./app/console --env=prod assetic:dump OK

WTF?

could anybody that uses assetic please try to do:

./app/console --env=prod cache:clear
./app/console --env=prod --no-debug assetic:dump

and see if any errors pop up.
Many thanks in advance.

it was my total fault. Sorry! :)

Had the same and found out that one of the getter was

public function(string $param)

which we all know is BAD !! Should have done

/**
 * xxxxxx
 * @var string $param
 **/
public function($param)

And no more error !!
