Jurgen Doll updated PDFBOX-5565:
--------------------------------
Description:
Currently if a PDF form text field has it's Comb flag set true but the max
length hasn't been set then PDFBox silently ignores the field and doesn't
render it.
It would be helpful for PDFBox to at least issue a warning that the field
cannot be rendered as a Comb due to this.
It may be worth noting that if pdForm.setNeedAppearances is set true, and after
setting fields pdForm.refreshAppearances() is invoked that Comb fields without
max length specified do display in Acrobat and Edge. However without both of
these conditions they also don't display, just like PDFBox currently.
Perhaps worth considering aligning PDFBox to behave in a similar fashion then,
and to still issue the warning.
