DITA PDF Transformation Fails
To generate the PDF output, Oxygen XML Developer plugin uses the DITA Open Toolkit.
You can analyze the Results tab of the DITA transformation and search
            for messages that contain text similar to [fop] [ERROR]. If you encounter
            this type of error message, edit the transformation scenario you are using and set
            the
            clean.temp parameter to no and the
            retain.topic.fo parameter to yes. Run the
            transformation, go to the temporary directory of the transformation, open the
            topic.fo file and go to the line indicated by the error. Depending on
            the XSL FO context try to find the DITA topic that contains the text that generates
            the
            error.
         
If none of the above methods helps you, go to and check what version of the DITA Open Toolkit you are using. Copy the whole output from the DITA OT console output and either report the problem on the DITA User List or to support@oxygenxml.com.
