Try this code. Have your Dynamic component selected, then run this in the web console:
model=Sketchup.active_model
entities = model.entities
sel = model.selection[0]
sel.attribute_dictionaries.each do |e|
puts "***DICTIONARY NAME***"
puts e.name
puts ""
puts "*****VALUES*****"
puts e.values
puts ""
puts "*****KEYS*****"
puts e.keys
puts ""
end
It will output to the Ruby Console, so have that open. That should show you some info.
