> Affects Versions: 2.7
> Reporter: peter royal
> Attachments: j2301.out, j2301.xml, j2301.xsl

> The XSL fragment that created this is:
> <xsl:apply-templates select="something>
> <xsl:sort select="@something"/>
> </xsl:apply-templates>
> resulting in:
> java.lang.NullPointerException

> ... then enters my code
> ... this occurs because the ElemSort has a single entry in its m_declaredPrefixes vector, an entry for 'xsl'.
> A 1-line fix to ElemForEach.java fixes this. In appendChild, when adding a sort element, just add:
> newChild.setParentElem( this );
> before returning the newChild.
