Problem in rendering two or more NmDefaultHTMLTables in one JSP page.

I have a JSP page where data is rendered using NmDefaultHTMLTable class. After the table is rendered I include two more JSPs at the bottom which in turn have their own tables which uses the same class NmDefaultHTMLTable.The problem is that when the JSPs are included they override the above table with their data. Is it not possible to render two or more NmDefaultHTMLTables in one page?

------------------Tabe 1 code snippet----------

NmDefaultHTMLTable table1 = new NmDefaultHTMLTable();

table1.addColumn();

table1.addCellValue();

NmDefaultHTMLTableModel Tmodel = (NmDefaultHTMLTableModel)table1.getModel();

table1.setTableModel(Tmodel);

modelBean.serModel(table1);

NmTableRenderer.draw(modelBean,,,,,,,);

modelBean.setModel(null);
