Hi John..
sorry for my stupid questions....
yes it works for me too(not adding the control_field using densha's
web ui, though):
<process-definition name="main_process" revision="1">
<sequence>
<participant ref="reader" />
<participant ref="dumper" />
<iterator on-value="${f:control_field}" to-variable="j">
<participant ref="toto" />
</iterator>
</sequence>
</process-definition>
the reader is a block partecipant defined in config/openwferu_partecipants:
$openwferu_engine.register_participant "reader" do |workitem|
puts "now insert new field name"
field_name = gets
field_name.chomp!
puts "now insert new field value"
field_value = gets
workitem.send("#{field_name}=", field_value)
puts "workitem's field value is #{ workitem.send("#{field_name}")
}"
end
( with this it doesn't work ... but it's due to the \n added by gets )
chomping! field_name after read all works fine and user is happy to
control at runtime iteration count....
$openwferu_engine.register_participant "dumper" do |workitem|
puts workitem.inspect
end
( this helped me to find what was wrong )
