---------------------------------------
Summary: Generate appearance stream for multiselect listboxes
Key: PDFBOX-3828
URL: https://issues.apache.org/jira/browse/PDFBOX-3828
Project: PDFBox
Issue Type: Improvement
Components: AcroForm
Affects Versions: 2.0.6
Reporter: Tilman Hausherr
Fix For: 2.0.7, 3.0.0
Attachments: SO44456172-AcroForm-empty.pdf, SO44456172-AcroForm.pdf
{{AppearanceGeneratorHelper.insertGeneratedSelectionHighlight()}} does not yet
support multiselect listboxes. Two other problems are that the positions are
incorrect (at least with the attached file), and that it insists on having at
least one element selected. IMHO it is allowed to have none element selected in
a listbox, see attached "empty" file, which I created by saving a file with
Adobe Reader that had "needAppearances" set.
I expanded the existing code for multiselect, and corrected the position
problem with some trial-and-error.
