Parameter defaults

[wmoore]

If I have a String parameter, I can specify the default like this:

scripts.String("Data_Type", default="Image")

but if I use a list I have to do

scripts.List("Channel_Colours", default=rstring("White"))

Unfortunately, this default is ignored by Insight.

The code below caused the script upload to fail with no validation exception:

scripts.List("Channel_Colours", default="White"),

[wmoore]

This is actually a bit of a problem, since Insight seems to ignore the default if it is wrapped in an rstring?

Or maybe Insight ignores defaults for lists of enums?

Will, I'm actually a little surprised that you can even call default=rstring() since the actual value needs to be a list. But ok, let's call that a feature. We could add a call to "wrap" which in the case of a string would work, but not a long. Probably the best thing to do is "encourage" the use of List.ofType and then we could use that type to do the casting, i.e. List(default="foo").ofType(rstring) or similar)

Could do that. I've not bothered to specify the type of list parameters if they're stings, but it seems reasonable to do it.

But, this doesn't work any better just yet:

scripts.List("Channel_Colours", default="White", values=cOptions).ofType(rstring(""))

Still need to wrap

default=rstring("White")
