list.unShift() doesn't work if the Array has only one value?

I recently discovered that in any new xPages, or on Domino 9, the list.unshift() function does NOT work if the list (array) only has one value. When did this break?

I need to be able to prepend a blank value in many combo boxes, even if the "list" in that field only has one value. How do you do that now?

I started with the older posts... looks like you made good progress on your own.

Again - Code really helps... I have no idea what this list.unshift() is or how it's being used.

IF your problem is you want to make sure everything returned back is an array... I wouldn't try to just prepend another value... I would try and convert the single value to an array. An array can hold one value.. I forget how to do that... but googling should get you there. on openntf there are some functions to force an @DbColumn and @DbLookup to an array so that would have an example there as well.

Good Luck!
