Multi-selection list box missing beginning items in Adobe Reader DC
Dear iText Mailing List Support:
iTextSharp.dll Version: 188.8.131.52
Adobe Reader DC Version: 2015.008.20082
Adobe Acrobat Pro Version: 8.x
I’m getting unwanted results in Adobe Reader when generating or regenerating a multi-selection list box in an Acroform PDF document. The resulting PDF views correctly in Adobe Acrobat 8, but not in Adobe Reader DC.
Problem: When viewing the modified PDF in Adobe Reader DC, the non-selected display items at the beginning of the list box that are previous to the first selection are hidden. For example: “One“,“Two“,“Three“,“Four“,“Five“ are list items; and “Two“ and “Four“ are selected; then previous items such as “One” are not visible in the top of the list box. And the first item displayed in the list box starts with the first selection, in this case “Two”. (See Adobe Reader DC Screenshot)
FYI: Using Adobe Reader DC, when I select different field selections in the list box, and then double click outside the list box, the list box field reverts back to normal appearance with all the items shown.
I can’t reproduce this issue when opening the modified PDF in Adobe Acrobat Professional 8 and all the field items are visible and correctly selected.
Is this an Adobe Reader DC issue or an iTextSharp issue?
