I need to add columns to an Xml data set based on comma delimeted list of parameters that will be passed to the report. I know I can do this to a scripted data set using this code:<br />
<br />
<br />
<pre class='_prettyXprint _lang-auto _linenums:0'>dataSet = reportContext.getReportRunnable().getDesignHandle();
dataSetHandleClone = dataSet.findDataSet("scripted");
log(dataSetHandleClone);
columnHint = dataSetHandleClone.getPropertyHandle("columnHints");
resultSet = dataSetHandleClone.getPropertyHandle("resultSetHints");
log("resultSet: " + resultSet);
ch = StructureFactory.createColumnHint();
ch.setProperty("columnName", "something");
ch.setProperty("displayName", "something");
columnHint.addItem(ch);
rs = StructureFactory.createResultSetColumn();
rs.setColumnName("test");
rs.setPosition(0);
rs.setDataType("String");
log("ResultSetColumn: " + rs);
resultSet.addItem(rs);
</pre>
<br />
However when I try to use this on an xml data set the resultset variable is null. Is there any way I can do this?
