Tilman Hausherr commented on PDFBOX-3257:
-----------------------------------------
I had the same problem with setProducer(), so it's not just for dates.
There's a bug in XMPSchema.setTextProperty():
{code}
if (nodeList.getLength() > 0)
{
Element node = (Element) nodeList.item(0);
node.setNodeValue(propertyValue);
}
else
{
Element textNode = schema.getOwnerDocument().createElement(propertyName);
XMLUtil.setStringValue(textNode, propertyValue);
schema.appendChild(textNode);
}
{code}
See this:
http://stackoverflow.com/a/4681358/535646
http://docs.oracle.com/javase/6/docs/api/org/w3c/dom/Node.html#setNodeValue%28java.lang.String%29
nodeValue is always null for {{Element}} objects, so the call to setNodeValue()
doesn't make sense.
this should be changed to
{code}
if (nodeList.getLength() > 0)
{
Element node = (Element) nodeList.item(0);
XMLUtil.setStringValue(node, propertyValue);
}
else
{
Element textNode = schema.getOwnerDocument().createElement(propertyName);
XMLUtil.setStringValue(textNode, propertyValue);
schema.appendChild(textNode);
}
{code}
> XMPSchemaBasic setCreateDate and setModifyDate don't work in some cases

> URL: https://issues.apache.org/jira/browse/PDFBOX-3257
> Project: PDFBox
> Issue Type: Bug
> Components: JempBox
> Affects Versions: 1.8.8, 1.8.11
> Environment: Suing pdfbox from maven
> Reporter: Svetlozar Argirov
> Priority: Minor
> Attachments: SJA Brochure February 2016 (DFV Edits).pdf

>
> When setting XMPSchemaBasic with in certain PDFs , setCreateDate and
> setModifyDate do not work if the dates are already set in the pdf.
> So this will not work as expected:
> {code:Java}
> XMPSchemaBasic bi = xmp.getBasicSchema();
> bi.setCreateDate(someDate);
> bi.setModifyDate(anotherDate);
> {code}
> Setting other metadata fields works as expected, except for these two.
> I found a workaround . If I set the fields to null, before setting them to a
> new value everything works as expected:
> {code:Java}
> XMPSchemaBasic bi = xmp.getBasicSchema();
> bi.setCreateDate(null);
> bi.setCreateDate(someDate);
> bi.setModifyDate(null);
> bi.setModifyDate(anotherDate);
> {code}
> But still it feels like there is something wrong with the way setting these
> two dates work.
