Isn't the problem that you're defining a list for the default in the
template, when it should be a string?

E.g:

security_group:
     type: comma_delimited_list
     label: 'Node ddddd Security Group(s)'
     default: default

If you need to specify additional items, they are delimted via commas, as
described in the type name, e.g 
 
security_group:
     type: comma_delimited_list
     label: 'Node ddddd Security Group(s)'
     default: default,blah

Heat then splits the string into a list when parsing the template.

Hope that helps.
