> Problems setting "on values" for PDCheckBox
> -------------------------------------------
>
> Key: PDFBOX-3406
> URL: https://issues.apache.org/jira/browse/PDFBOX-3406
> Project: PDFBox
> Issue Type: Bug
> Components: AcroForm
> Affects Versions: 3.0.0
> Reporter: Mark Melling
>
> I'm not entirely sure if this is a bug or I'm doing something incorrectly.
> I'm trying to create a PDCheckBox, which I can then subsequently call check()
> on, but when I create a "vanilla" PDCheckBox and then call check() on it I
> get the error:
> IllegalArgumentException value 'Yes' is not a valid option for the field
> initial-assessment, valid values are: [] and Off
> I then tried to use setExportValues() as looking at the code it looked like
> this would do the trick. Unfortunately checkValue() which is called at the
> start of setValue() fails, as whilst the PDButton version of getOnValues
> checks if their are any export values, the PDCheckBox version doesn't and for
> this reason fails.
> I then tried to create a dictionary of values by using setNormalAppearance on
> the PDAppearanceDictionary of the CheckBox's widget. In the dictionary I just
> created an entry using setName ("Yes", ""). Initially this didn't work as
> getSubDirectory of PDAppearanceEntry filters out any entries that don't have
> a value which is an instance of COSStream. I resolved this by simply creating
> a empty COSStream value, but this didn't feel right, particularly given that
> the value is not even used in this context (if I understand the code
> correctly).
> Given all of this I suspect I'm doing this all wrong, but it's not clear what
> the right way to do it is.
