             Summary: Can't draw color border around a PDTextBox + create example
                 Key: PDFBOX-2830
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2830
             Project: PDFBox
          Issue Type: Bug
          Components: AcroForm, PDModel
    Affects Versions: 2.0.0
            Reporter: Tilman Hausherr


There's a thread "Setting a border color on a PDTextBox" in the user mailing list. This relates to version 1.8.*, but I wanted to create an example for 2.0. After doing this for 2.0 with this code
{code}
PDAppearanceCharacteristicsDictionary fieldAppearance = 
                new PDAppearanceCharacteristicsDictionary(new COSDictionary());
        PDColor green = new PDColor(new float[] { 0, 1, 0 }, PDDeviceRGB.INSTANCE);
        fieldAppearance.setBorderColour(green);
        widget.setAppearanceCharacteristics(fieldAppearance);
{code}
it didn't work. The reason is this in the PDF:
{code}
5 0 obj
<<
/FT /Tx
/T (SampleField)
/Type /Annot
/Subtype /Widget
/Rect [50.0 750.0 250.0 800.0]
/MK 7 0 R
/V (English form contents)
/AP 8 0 R
>>
endobj
6 0 obj
<<
/Font 9 0 R
>>
endobj
7 0 obj
<<
/BC [0.0 1.0 0.0 null]  <===================
>>
endobj
{code}
The /BC color array has an extra null element. Removing it brings a "good" file. I believe this is a regression that came from changing PDGamma to PDColor some time ago.
