Behat/Mink not finding a default step for a "Then" statement - php

Question

I cannot get Mink/Behat to find the default step for the phrase
Then I should see "some text" in the element "element"
Here is my thepage.feature file:
Feature: Page Works
In order to use the page
As a visitor
I need to be able to load it and see content
Scenario: Navigating to the page
Given I am on "mypage.php"
#Then I should see "some text"
#Then the "body" element should contain "sometext"
#Then I should see "sometext" in the "body" element
My FeatureContext extends MinkContext so I don't see why the lower two Then statements come up as undefined, but the upper one works.
Scenario: Navigating to the page # features\wikipedia.feature:6
Given I am on "thepage.php" # FeatureContext::visit()
Then I should see "sometext" in the element "body"
1 scenario (1 undefined)
2 steps (1 undefined)
Since the Given statement works, I don't understand what could be wrong! Surely it can't be the yml file or composer.json?
composer.json:
{
"require": {
"behat/behat": "2.4.*#stable",
"behat/mink": "1.4.*#stable",
"behat/mink-extension": "*",
"behat/mink-goutte-driver": "*",
"behat/mink-selenium2-driver": "*"
},
"minimum-stability": "dev",
"config": {
"bin-dir": "bin/"
}
}
behat.yml:
default:
extensions:
Behat\MinkExtension\Extension:
base_url: http://localhost
goutte: ~
selenium2: ~
Where else could the problem be? Thanks

Answer 1

Try to use
Then I should see "sometext" in the "body" element
instead of
Then I should see "sometext" in the element "body"
Here is MinkContext method description

Try with these (got it from here):
composer.json
"require-dev": {
"behat/behat": "2.5.5",
"behat/mink-extension": "1.3.3",
"behat/mink": "1.5.0",

"behat/mink-selenium2-driver": "1.1.1",
"behat/mink-browserkit-driver": "1.1.0",
"behat/mink-goutte-driver": "1.0.9"
}
behat.yml
default:
formatter:

context:
class: Application\BackendBundle\Features\Context\FeatureContext
extensions:
Behat\Symfony2Extension\Extension:
mink_driver: true
