Setting the value of a single-select PDChoice field
Hi,
I'm using PDFBox to automatically fill in all kinds of PDF documents. Recently, I was seeing the following error message with a new PDF:
'The list box does not allow multiple selections.'
I saw in the code that the PDChoice field can be single-select or multi-select. With single-select fields, the setter that takes a list of choices [0] throws an exception whenever the given list is not empty. Therefore I now have to use the general setter from PDField [1] which does not check whether the provided option is valid (selectable).
It would be great if the setter from [0] would also work for single-select choices and would only throw an exception if the list's size is greater than 1.
Any thoughts on this?
Thanks & Regards
Oliver

@Tilman I agree that setting an illegal option is the only bug here.
The other issue is more a matter of convenience. In my case I'm mapping HTML form data to PDFs, to be precise: input from <select> fields to PDChoice / PDComboBox fields. Both fields can be single or multi-valued. Ideally, I would work transparently with lists here and only expect errors when I try to set more than one entry on a single-valued PDChoice.
@Maruan You're correct, that's what I was trying to ask.

If I understand the question correctly it's about being able to use the
List based setter with a single select option field if the List has a
single entry. If the List has more than one entry still throw the
exception.
Is that correct?

IMHO the only bug is that a setter can set an illegal option.
The rest looks fine to me, a user should know what field they are filling.
