Answer 1

It is a model and cache issue (reset all configuration and erase model and data files)

rm config/doctrine/schema.yml
rm -r cache/*
rm -r data/*
rm -r lib/model/doctrine/base

symfony cc

I found a second response, using builder.php patch to have doctrine object getters in symfony 1.2 cast this error also.
