             Summary: PDPushButton.getOnValues() throws IllegalStateException
                 Key: PDFBOX-4825
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4825
             Project: PDFBox
          Issue Type: Bug
          Components: AcroForm
    Affects Versions: 2.0.19, 2.0.20
         Environment: Windows 10 (v10.0.18363.778)
openjdk version "11.0.4" 2019-07-16
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.4+11)

Calling PDPushButton.getOnValues() results in an IllegalStateException in v2.0.19 and v2.0.20-SNAPSHOT). Not sure if prior versions exhibited this error. Line numbers are identical in both tested versions.  
{code:java}
java.lang.IllegalStateException: This entry is not an appearance subdictionary

at org.apache.pdfbox.pdmodel.interactive.form.PDButton.getOnValueForWidget(PDButton.java:349)
at org.apache.pdfbox.pdmodel.interactive.form.PDButton.getOnValues(PDButton.java:320)
at AppearanceSubdictionaryError.main(AppearanceSubdictionaryError.java:21){code}
 

Sample file attached to issue was created utilizing Adobe Acrobat Standard DC 20.6.20042.

Sample code to reproduce:

 
{code:java}
import java.io.File;
import java.io.IOException;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.interactive.form.PDField;
import org.apache.pdfbox.pdmodel.interactive.form.PDPushButton;
public class AppearanceSubdictionaryError
{
    public static void main(String[] args) throws IOException
    {
        PDDocument document = null;
        try
        {
            document = PDDocument.load(new File("testimage.pdf"));
            for (PDField field : document.getDocumentCatalog().getAcroForm().getFields())
            {
                if (field instanceof PDPushButton)
                {
                    ((PDPushButton) field).getOnValues();
                }
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
        finally
        {
            document.close();
        }
    }
}
{code}
 

Ran across this issue when pulling acro field information from a test document. This doesn't affect our use of the project. I am merely reporting it as it seems like it shouldn't happen.
