Hi,
I am trying to add a tag to a table in pptx. (I used this sample code (https://svn.apache.org/repos/asf/poi/trunk/src/ooxml/testcases/org/apache/p oi/xslf/usermodel/TestXSLFPictureShape.java) for my test.) I did it like this .... XSLFTable table = slide.createTable(); // Set up the table columns, rows etc. ....... CTGraphicalObjectFrame ctT = table.getXmlObject(); ctT.getNvGraphicFramePr().getNvPr().addNewCustDataLst().addNewTags().setId(" rId99"); When this last line is added I cannot open the pptx document, since a message is displayed: PP found a problem with content in TestTable.pptx. PP can attempt to repair the presentation. I assume that I miss to create the necessary tag reference (which would be in the tags folder in the pptx file), but I cannot find the way how to do it. Could somebody give me an advise how to solve the above problem. Thanks in advance for your time, Erzsebet
