esql get-colums nullpointerexception

[Matthew Cordes <mc...@maine.edu>]

Hello all.  I'm getting a null pointer exception when using 
<esql:get-columns/> on columns that contain null values.  It seems to
me this is the offending bit of code:


        for (int _esql_i=1; _esql_i &lt;= _esql_query.resultset_metadata.getColumnCount(); _esql_i++) {
          Node _esql_node = document.createElement(_esql_query.resultset_metadata.getColumnName(_esql_i));


				/** get-string-encoded appears to return a null string, 
						which when added to the dom causes the exception */

          _esql_node.appendChild(document.createTextNode(
            <xsl:call-template name="get-string-encoded">
              <xsl:with-param name="column-spec">_esql_i</xsl:with-param>
              <xsl:with-param name="resultset">_esql_query.resultset</xsl:with-param>
            </xsl:call-template>


          ));
          xspCurrentNode.appendChild(_esql_node);
        }


I propose something like this:

String nodeText = String.valueOf(
	<xsl:call-template name="get-string-encoded"
		<xsl:with-param name="column-spec">_esql_i</xsl:with-param>
		<xsl:with-param name="resultset">_esql_query.resultset</xsl:with-param>
	</xsl:call-template>
);

if ( nodeText != null )
{
	_esql_node.appendChild( document.createTextNode( nodeText ));
	xspCurrentNode.appendChild(_esql_node);
}
	
Anyone else have this problem?
