Søren ,
May I ask you a follow up? I am trying what I thought I read in your reply
(thank you for that, by the way). But I continue to get this error:
"The LHS of an assignment should be a variable or a field accessing
expression @ ...."
This is what I currently have, attempting to set my variable name to
include the key drawn from my Groovy map. How must I change this to get it
to work?
mapLanguages.each { k, x ->
log.warn('mapLanguages entry is this: {} {}', ["$k", "$x"] as
Object[])
x.each {
languageChar -> log.warn('language char in {} is this: {}',
["$k", "$languageChar"] as Object[])
}
"contains${k}" = true
}
Many thanks again,
Jim
