Table duplication

Hi all,

          In the below code I created a duplicate table. But how can I pass that duplicate table in dictTable = new  DictTable(---?????--);

--------------------------------------------------------------

DictTable  dictTable;

Common common;

dialogSource = dialog.addField(extendedTypeStr(TableName),"DataSourceTable");

treeNode = TreeNode::findNode(#TablesPath);

treeNode.AOTfindChild(dialogSource.value()).AOTDuplicate();

SqlDataDictionary::synchronize();

dictTable = new  DictTable(---?????--);

common = dictTable.makeRecord();

Thanks & Regards,

Rk.
