Hello,
you can nest dollar expressions:
---8<---
concurrent_iterator :on => '${f:coauthor_emails}', :tag => 'coauthor_forms',
:to_var => 'v' do
concurrence do
participant 'coauthor-${v:v}', :task => 'complete_information', :unless =>
'${${v:v}_info_present}'
participant 'coauthor-${v:v}', :task => 'submit_copyright'
participant 'coauthor-${v:v}', :task => 'submit_disclosure'
end
end
--->8---
Your version always resolved to something like:
participant '[email protected]', :unless => '[email protected]_info_present'
which got skipped since an non-empty string is considered true.
The nested version should resolve (second to last resolution) to:
participant '[email protected]', :unless => '${[email protected]_info_present}'
Which will get skipped if the workitem field '[email protected]_info_present' holds
a trueish value.
