[jira] [Comment Edited] (PDFBOX-4825) PDPushButton.getOnValues()
throws IllegalStateException
[ https://issues.apache.org/jira/browse/PDFBOX-4825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17102817#comment-17102817 ]

Thank you... this is a Pushbutton, this type of button retains no permanent value, so I think it shouldn't return any "on" values. I think we should add methods in the class to return an empty list for getOnValues() and "" for getOnValue().
