Scriptrunner Behaviour - remove select list options but keep "None" option

[Chris Sharpe]

I want to restrict a subtask's Project Specific Select Field custom field options based on other peer subtask's values in the same field. I'm not sure that PSSF custom field type matters here versus a standard select list, but wanted to mention it anyway.

The code below mostly works as expected. I can create a subtask and get all possible options (e.g. "A", "B", "C") for Target Release field. I choose "A" for this subtask. When I create a second subtask, I am presented with the full list of options minus the one I selected in the first subtask (i.e. "B", "C").

However, this is a required field. So normally the form would also present a "None" option as the selected value and thus force the user to make a choice here.  But with the behaviour active, "None" gets removed.  This basically makes a selection by default and also means other things don't trigger as they normally would on field change.

So I added the line to explicitly add "None" to the options list.  Now, it shows TWO None options.  So with my code to prune the choice list, I can either have no None value or two None values.  How do I get the pruned list plus a single default None entry (that's not a valid choice)?

Hello, is there any update on this issue?

I see the same double "None" options issue in select list, when I add "None" option manually in ScriptRunner v. 8.33.

In my case select list is a TextField converted to SingleSelect in ScriptRunner Behaviours:

def customField = getFieldById("customfield_123");
customField
    .convertToSingleSelect([css: "max-width: 500px; width: 500px; white-space: pre-wrap;"])
    .setFieldOptions(["":"None", "option1":"Option 1"]);
