Subject [jira] [Commented] (PDFBOX-4399) Printing invisible Content from PDF-Forms
Date Mon, 10 Dec 2018 18:03:00 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-4399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16715250#comment-16715250
] 

Stefan Ziel commented on PDFBOX-4399:
-------------------------------------

The javascript as far as it concerns just states some OCG's to true and others to false and
vice versa depending on the button the user clicked. 
{code:java}
function lang_de()
{
	var aOCGs = this.getOCGs() ;
	for (var i = 0 ; i < aOCGs.length ; i++)
	{
		if (aOCGs[i].name == "de")
		{
			aOCGs[i].state = true ;
		}
		
		if (aOCGs[i].name == "fi")
		{
			aOCGs[i].state = false ;
		}
	}
       ...
}
{code}
The issue is identical to what described by the external links posted by [~tilman].
