Maruan Sahyoun commented on PDFBOX-2961:
----------------------------------------
added PDField.getWidgets() for the 1.8 branch to make it easier to get all
widgets associated with a field. I won't be enhancing the check()/uncheck()
methods to use the new method as this would be an API braking chance because of
the IOException being potentially thrown.
> Checkbox with multiple widgets doesn't reflect check() state.

> If a checkbox has multiple annotations (i.e. the same checkbox field occurs
> multiple times within the form) the appearance state for the annotation
> widgets is not correctly set.

> Hi,
> I have a simple document with two PDCheckbox fields, and one of those fields
> has two AnnotationWidgets. I am able to successfully call check() on the
> first field and see the result in the output document, but calling check() on
> the field with multiple AnnotationWidgets has no effect.
> My understanding of duplicated fields is that only a single PDField exists
> but that an AnnotationWidget kid will exist for each instance of the field in
> the document, so setting the PDField parent once should affect all of the
> children. Am I misunderstanding how this should work?
> Attached is the document I am testing as well as a small Java class that
> reproduces the issue by calling check() on everything in getFields(). I have
> tried this with PDFBox 1.8.9, 1.8.10, and the 09/03 Snapshot of 2.0.0. I am
> viewing the document with Adobe Acrobat Reader DC Version 2015.008.20082.
> Any insight would be appreciated.
> Thanks,
> Bart.
