Null pointer exception for "Normal" style using sample code

[mmoselhy]

Hi,

I wanted to print the style name for paragraph in the sample document "sample-docx.docx"
using openMainDocumentAndTraverse.java with little modification in the callback method to be

Code: Select all

public List<Object> apply(Object o) {
            
            String text = "";
            if (o instanceof org.docx4j.wml.Text)
               text = ((org.docx4j.wml.Text) o).getValue();
               
            
            if (o instanceof org.docx4j.wml.P)
               text += "=====" + "  " + ((org.docx4j.wml.P) o).getPPr().getPStyle().getVal();
            
            System.out.println(indent + o.getClass().getName() + "  \""+ text + "\"");
            return null;
         }

I get null pointer exception in this text "This is a document exhibiting basic docx features. " which style is Normal as there is no ppr object for this Paragraph

Why do I get this error ? or how can I get what I wanted to do ?


Thanks

Paragraphs which aren't styled use the default paragraph style (ie Normal).

Just check getPPr()!=null before doing getPStyle()
