Help converting UIX JSP functionality to UIX

Question

I have an older UIX JSP page that I am trying to convert to UIX. That page contained a table with a singleSelection node and a Print button. When the Print button is pressed, a value is taken from the selected row in the table and sent as a parameter to Oracle Reports. The code that did this in UIX JSP is:
<jbo:OnEvent name="Print">
<% if(sSelected != null)
errmsg = null;
errtype = null;
%>
<jbo:Row id="MPORow1"
datasource="MPOOrders"
action="Find"
rowkey="<%= sKey %>" />
<%
Row MPOCurRow1 = MPOOrders.getRowSet().getCurrentRow();
if (MPOCurRow1 != null)
String ordnum = (String) MPOCurRow1.getAttribute("Ordnum").toString();
String mailer = (String)((Integer) session.getAttribute("loginCustomer")).toString();
String printURL = "https://<myserver>/reports/rwservlet?destype=cache+desformat=PDF+userid=webuser/webpwd@pas+report=mlrjobstatus.rdf+p_mailer=" + mailer + "+p_jobnum=" + ordnum;
response.sendRedirect(response.encodeRedirectURL(printURL));
else
errtype = "error";
errmsg = "You must select a row prior to clicking on the 'Print Lists' button";
%>
</jbo:OnEvent>
How can I do this same thing in UIX/Struts? Can it be done as a UIX handler or do I need a custom DataAction?

Hi Eric,
Please take a look at the UIX Table chapter. It talks about single-selection in UIX and how you can add buttons which when clicked will submit events to the server. It also talks about how you can handle those events.
Here is a code snippet from the documentation regarding the event handler:
public static EventResult doSelectionEvent(BajaContext bc, Page page,
                                           PageEvent event)
  DataObject tableRows = new PageEventFlattenedDataSet(event, "table1");
  int index = SelectionUtils.getSelectedIndex(tableRows);
  String name = "Nothing Selected";
  // make sure that something was selected:
  if (index>=0)
    DataObject row = _TABLE_DATA.getItem(index);
    name = row.selectValue(null, "name").toString();
  EventResult result = new EventResult(page);
  result.setProperty("action", event.getName());
  result.setProperty("name", name);
  return result;
}Thanks,
Jeanne
