Hi,

I am trying to loop through database results and render a grid that has grouping on a page. The group label should be a term and the group rows should display all the possible uses of this term. The possible uses of a term are stored as pipe delimited text in the database. This is my Java code:

public void populateGlossary() { Rows rows = new Rows();
glossary.appendChild(rows);

 Group cGrp = new Group("GlossaryTerm1:");
 cGrp.setVisible(true);
 cGrp.setOpen(true);
 glossary.getRows().appendChild(cGrp);

 Row cRow = new Row();
 cRow.appendChild(new Label(""));
 cRow.appendChild(new Label("Explanation of term1"));
 glossary.getRows().appendChild(cRow);

 List glossaryResults = executeNamedQuery("getGlossary", null, null);

 for (int i=0; i < glossaryResults.size(); i++) {
      Object[] dataObj = (Object[]) glossaryResults.get(i);

      Group grp = new Group(dataObj[0].toString());
      grp.setVisible(true);
      grp.setOpen(true);
      glossary.getRows().appendChild(grp);

      String[] codeUses = dataObj[1].toString().split("\\|");
      for (int j=0;j<codeUses.length;j++) {
           Row row = new Row();
           row.appendChild(new Label(""));
           row.appendChild(new Label(codeUses[j].toString()));
           glossary.getRows().appendChild(row);
      }
 }

}

My jsp page is: <z:grid id="glossary" mold="paging" pagesize="50" pagingposition="both" emptymessage="There is currently no glossary available."> <z:columns sizable="true"> <z:column label="Code" width="30%"/> <z:column label="Code Use" width="70%" align="left"/> </z:columns> </z:grid>

The grid displays fine...but there is no Expand/Collapse button next to the Group Label. The Group looks like a row. What I am doing wrong?

Thank you for your time.
