Unable to call a step - that takes an application_environment object as a param - from stage block

[Vince-Cercury]

In my pipeline_config:

application_environments{
    dev{
        long_name = "Development"
    }
    prod{
        long_name = "Production"
    }
}

I've got a step called project_specific_step.groovy:

void call(environment) {
   echo "environment.short_name: ${environment.short_name}"
}

Calling it from Jenkinsfile:

project_specific_step dev

OUTPUT:

environment.short_name: dev

As expected

Calling it from a stage block defined in pipeline_config.groovy:

stages{
  stage_do_things{
    project_specific_step dev
    common_step_a
    common_step_b
  }
}

OUTPUT:

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: org.boozallen.plugins.jte.binding.injectors.ApplicationEnvironment.call() is applicable for argument types: () values: []
Possible solutions: wait(), any(), wait(long), any(groovy.lang.Closure), each(groovy.lang.Closure), wait(long, int)

Error.

Is passing an application_environment object to a step supported from a stage block?

Use case: Only one of my project need to call project_specific_step step. The others don't. I want to reuse the same Jenkinsfile though. I don't want to have to create another Jenkinsfile just for that one project that is different. So overriding a stage block primitive in pipeline_config of this specific project is ideal.
However my step needs an input, as it is being called a few times, in different stages. Behaviour will change depending on the environment we pass

Suggestions please?

Recapping the conversation from the JTE Gitter Channel:

Stage parameters should be passed from the pipeline template and accessed in steps via the stageContext variable.

This stageContext functionality has been documented as part of the 2.0 release.
