Checking of row number

Question

I am using jdeveloper 11.1.2
I have have jsff page with table in it
I can check if this table contain rows using el just like that
#{bindings.SubmitDCIterator.estimatedRowCount != 0}
where SubmitDCIterator is the iterator on this table
but I need to check using el if there are rows with specific condition like the field status = 2
how can I do that

Answer 1

You need something in your model to estimate whether there is any row with status=5.
Try to add this code to your ViewObjectImpl class:
private class AgrFuncHelper extends HashMap
  private String funcName;
  public AgrFuncHelper(String funcName)
    super();
    this.funcName = funcName;
  public Object get(Object key)
    return InvokerHelper.invokeMethod(getDefaultRowSet(), funcName, key);
public Map getSum()
  return new AgrFuncHelper("sum");
public Map getCount()
  return new AgrFuncHelper("count");
}And the EL expression should look like this:
rendered="#{bindings.YourVO1.viewObject.sum['Status==5 ? 1 : 0']}"AP
