Hi All,

It seems like issues along these lines have been raised as bugs and closed 
several times... see https://github.com/ansible/ansible/issues/17500


I have created a role, which I intend to skip under certain circumstances. 
When the role is skipped, all tasks still run... OK... I don't understand 
why this is desired behavior but that's beside the point. I have ended up 
needing to put some very nasty looking "|default()" filters inside of my 
"with_items" clauses to get the playbook to run. Without the default values 
I end up with errors like 'dict object' has no attribute 'stdout_lines'

Any other suggestions? I guess I can have different playbooks for different 
roles rather than skipping roles that I don't want to use, but it seems a 
little cumbersome.

Thanks, 
Paul
