convertToMultiSelect only saves the last selected value

[John W]

We have a simple Behaviour to convert a single select field to a multi-select: 

getFieldByName("Craft").convertToMultiSelect()

When I edit an issue using this Behaviour, I can select multiple values but only the one I choose last is actually saved, and no more than one value is ever saved.

I tried it this way too, but no change:

getFieldByName("Craft").convertToMultiSelect([ 
ajaxOptions: [
query: true, // keep going back to the sever for each keystroke
minQueryLength: 0, 
keyInputPeriod: 500, 
formatResponse: "general", 
]
])

We're running Scriptrunner 6.0.0-p5 on Jira Service Desk 4.6.1.

You cant convert single select to multi select. It may have the same appearance but you cant store multiple values in a single select select list field.

You must have a text field to do that.

The ScriptRunner documentation for this is pretty bad - they never mention it must be a text field. Hell, in their "Walkthroughs", they never even attach it to a field. But, they do show a screenshot of it working and the field name they use throughout is called "TextFieldB" (or similar). So, you can figure it out, if you try. Still, pretty bad on their part.

How about any documentation for the `convertToMultiSelect` method at all? All we get are examples that happen to use options. Where is the list of all the options?

Why does this use the keys when displaying?

Are both text and html required for "general" responses?

Pretty terrible solution, imo.

What is the current field type which you are converting ?

Like I said, it's a single select.
