Show message dialog before options are displayed

Hi,

I am writing a `SequenceAnnotationGenerator` and would like to require that a sequence range be selected before displaying the `Options` dialog.

I am currently able to do this check within `generateAnnotations()`, which has access to the `SelectionRange`, but by the time this is called the user has already completed the `Options` dialog. I would like the check to come before the options, display a message and then return the user to the sequence viewer to select some sequence.

Thanks!

  Hi Pam,

  If you are creating a SequenceAnnotationGenerator then you should be overriding a getOptions() method in order to create your options. There is a method of getOptions which has a SelectionRange passed into it so I would recommend checking if the selectionRange is null as the first thing to do when you override that method.
  For example something like this:

  @Override
  public Options getOptions(AnnotatedPluginDocument[] documents, SelectionRange selectionRange) throws DocumentOperationException {
      if (selectionRange == null){
          throw new DocumentOperationException("You must select a selection range");
      }
      ...
      ...
  }

  Let us know if that works out for you!

  Cheers,
  Tom
