Hi,

Context:

I am creating a custom options dialog box. I want to incorporate "add Documents to workflow" like option to the dialog box.

Question:

Is addDocumentSelectionOption the right method? Can someone provide an example of how to use DocumentSelectionOption?

Thanks!

  Yes, addDocumentSelectionOption is a good way to do it.

  Here's and example using it to specify one additional sequence document:

  //add the option
  List<DocumentField> fieldsToDisplay = Arrays.asList(DocumentField.DESCRIPTION_FIELD, DocumentField.SEQUENCE_LENGTH);
  DocumentSelectionOption documentSelectionOption = options.addDocumentSelectionOption("additionalSequence", "Addition Sequence:", DocumentSelectionOption.FolderOrDocuments.EMPTY,
  DocumentType.NUCLEOTIDE_SEQUENCE_TYPE, fieldsToDisplay, false, Collections.emptyList());
   
  //get its value
  AnnotatedPluginDocument additionalDocument = documentSelectionOption.getDocuments().get(0);

  With the code block above, I receive a NullPointerException with the null default value parameter. How would I resolve this?

  (I want to reproduce below)

  Sorry about that, you can use the following for an empty selection instead of null:

  DocumentSelectionOption.FolderOrDocuments.EMPTY
