Yes, this is intentional. It is difficult to know what the default action should be when concatenating a list of values into a string so we don't do it by default. > I’ve created a bug ticket for it on github > (https://github.com/impactcentre/interoperability-framework/issues/18), > and added an if statement to handle lists. > > Is there a method to loop over the lists and get the results as a String? > > Any pointers will be appreciated, The best thing to do would be to get the value of the output (which in this case is a list) and loop over it concatenating it however makes most sense for you. If you look in the next branch of the t2-server-java-cli project (https://github.com/myGrid/t2-server-java-cli/tree/next) you can see an example of this in GetOutput.java Something like (where 'port' is your output port): StrBuilder data = new StrBuilder(); for (AbstractPortValue p : port.getValue()) { data.append(p.getDataAsString()) } String list = data.toString(); You'll have to adjust this for outputs with depth > 1 too. I hope this is OK for now. I realise that there is a gap in the API here where list outputs are concerned but the potentially infinite depth of ports needs thinking about too. If you have any suggestions we'd be pleased to hear them!
