[Flow] Set Sub-Context with TYPO3.Surf

[David Sporer]

Hi,

I’m trying to deploy a Flow application and want to use Production/Staging as Context.
Means I have folder structure like this:
Configuration/
	Production/
		Staging/
			Settings.yaml

This is working fine if I’m setting the context in my .htaccess file (SetEnv FLOW_CONTEXT Production/Staging).
But if I try to set it in my Surf Deployment definition with either one of the following:
- $application->setContext('Production/Staging');
- $application->setOption('defaultContext', 'Production/Staging');

I get an error during deployment when typo3.surf:typo3:flow:migrate is executed. The error is 
Could not write configuration cache file  /Configuration/Production/Staging/IncludeCachedConfigurations.php
which is strange because even if I set permissions to 777 the error occurs.

If I use $application->setOption('defaultContext', 'Production/Staging‘);
the error is
PHP Fatal error:  Call to undefined method TYPO3\Flow\Core\Bootstrap::getEnvironmentConfigurationSetting() in /releases/20150621145122/Packages/Framework/TYPO3.Flow/Scripts/flow.php on line 52

Does one of you guys have an idea how I can set the context? Or is only Development, Testing and Production possible?

Regards,
David
