Methods setIdAttribute(), setIdAttributeNS() throw NullPointerException

Name: eaR10174 Date: 09/04/2003


  The methods Element.setIdAttribute(), Element.setIdAttributeNS() throw
NullPointerException in case when the parameter name does not match any name of element
attributes (see test.java below). According to the methods javadoc
  
     public void setIdAttribute(String name,
                           boolean isId)
                    throws DOMException
                    
      ...
                    
      Throws:
       DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
       NOT_FOUND_ERR: Raised if the specified node is not an attribute of this element.


     public void setIdAttributeNS(String namespaceURI,
                             String localName,
                             boolean isId)
                      throws DOMException
                      
      ...

      Throws:
       DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
       NOT_FOUND_ERR: Raised if the specified node is not an attribute of this element.

the methods should throw DOMException with the error code NOT_FOUND_ERR.

  The bug appears in jdk1.5.0beta-b18 and affects new JCK1.5 tests:
  
      api/org_w3c/dom/Element/index.html#SetIdAttribute[SetIdAttribute004]
      api/org_w3c/dom/Element/index.html#SetIdAttribute[SetIdAttributeNS004]
