Unhandled Exception - getXmlTemplate().replaceAll()

Hi!

The indidated line below gives me this error:
            org.apache.struts.action.RequestProcessor processException
                WARNING: Unhandled Exception thrown: class java.lang.NullPointerException

and this is getXmlTemplate() is just getter function.
++++++++++++++++++++++++      
public ActionForward create(ActionMapping mapping,
                                                       ActionForm form,
                                                       HttpServletRequest request,
                                                       HttpServletResponse response)
                  throws Exception {
                        
                        String typeId = request.getParameter("testSelection");
                        
                        AssessTestTypeDAO typeDAO = new AssessTestTypeDAO();
                        AssessTestType type = typeDAO.select(typeId);
               
                        typeDAO = null;
                        if (type != null)
                        {
                              
                            String xml = type.getXmlTemplate().replaceAll("\t|\n", ""); ------> error
                            String xsl = type.getHtmlXSLFile();

You are checking that type != null but not "type.getXmlTemplate() != null".

When you call replaceAll on the String returned by .getXmlTemplate() it is failing as it is returning a null not a String.
