Hi,
I have a JSF 1.2 and I invoke my report from managed bean. My report contains custom handler:
public class MyTableHandler extends TableEventAdapter {
public void onCreate(ITableInstance table, IReportContext reportContext) {
}
public void onPrepare(ITable table, IReportContext reportContext) {
}
public void onRender(ITableInstance table, IReportContext reportContext) {
}
}
My question is : what is the best way to pass any object from managed bean (in my example there is a List<Employees> ) and get it in onCreate() method ? Is there any way to set this object to IReportContext ?

Hi,
this is my manged bean code
public class PageBean implements Serializable{
private List<Employee> emp;
@SuppressWarnings("unused")
@PostConstruct
private void init(){
emp = EmployeeDAO.getEmployees();
}
public void runReport(ActionEvent evt){
String url = "/frameset?__report=WEB-INF/birt/DemoReport.rptdesign&__fittopage=true";
FacesContext context = FacesContext.getCurrentInstance();
HttpServletRequest req = (HttpServletRequest) context.getExternalContext().getRequest();
HttpServletResponse resp = (HttpServletResponse)context.getExternalContext().getResponse();
req.setAttribute("AppContextKey", "EmpList");
req.setAttribute("AppContextValue", emp);
try {
req.getRequestDispatcher(url).forward(req, resp);
} catch (ServletException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
and this is my event handler class for Scripted Data Source
public class EmployeesTableHandler extends ScriptedDataSetEventAdapter {
private List<Employee> employees;
private int rows = 0;
@SuppressWarnings("unchecked")
@Override
public void beforeOpen(IDataSetInstance dataSet, IReportContext ctx){
employees = (List<Employee>)ctx.getAppContext().get("EmpList");
}
@Override
public boolean fetch(IDataSetInstance dataSet, IUpdatableDataSetRow row) {
try {
if(rows == employees.size()){
return false;
}
Employee emp = employees.get(rows);
row.setColumnValue("FirstName", emp.getFirstName());
row.setColumnValue("LastName", emp.getLastName());
row.setColumnValue("Age", emp.getAge());
rows++;
return true;
} catch (ScriptException e) {
e.printStackTrace();
return false;
}
}
}
But ctx.getAppContext().get("EmpList")
Folowing code works as expected
public void beforeOpen(IDataSetInstance dataSet, IReportContext ctx){
employees = EmployeeDAO.getEmployees();
}
So, the problem is with requested params.

Kuba,
As a test could you change your url
/frameset to /preivew and try the request object again?
