Re-Query Iterator is not working (I tried everything)

Question

Hi,
I'm trying to re-query an iterator with not luck, the first time it works well, but the second time it return the same data, this is the actual code:
    private static Row[] getSystems(String releaseId) {
        BindingContainer bc = BindingContext.getCurrent().getCurrentBindingsEntry();       
        OperationBinding op = bc.getOperationBinding("ExecuteWithParams3");
        op.getParamsMap().put("param_id", paramId);
        op.execute();
        DCIteratorBinding iter = (DCIteratorBinding)bc.get("Iterator");
        Row[] mappedSystems = rowSetItertor.getAllRowsInRange();
        return mappedSystems;
    }I tried things like this:
In the property inspector set the iterator's refresh property to never never and cache to false false, the result its that the first time everything is fine, second time I don't have more info at the iterator.
Call this metods:
// Nothing
iter.executeQuery();
// It clears the data, but after that I can't obtain data from db.
iter.getViewObject().clearCache();
// Nothing
iter.getViewObject().resetExecuted();
// Nothing
iter.executeQuery();
iter.refresh(DCIteratorBinding.RANGESIZE_UNLIMITED);
// Nothing
iter.setRefreshOption(0);
//Nothing
iter.setRefreshOption(8192);
// Tried to close the iterator set, second time it doesn't contain anything.
RowSetIterator rowSetItertor = iter.getRowSetIterator();
Row[] mappedSystems = rowSetItertor.getAllRowsInRange();
rowSetItertor.closeRowSetIterator()Basically when the user clicks a button this code is call with the appropriate parameter, this must retrieve a row's list. This code is called in a ManageBean with TaskFlow scope.
Any help would be great, thanks in advance.

P.S JDeveloper 11.1.1.4.0 & I also tried all the suggestions listed in this thread: Refresh Vo Iterator

Answer 1

I did this but nothing (because I need to send the "param_id").
private static Row[] getSystems(String releaseId) {
        BindingContainer bc = BindingContext.getCurrent().getCurrentBindingsEntry();       
        OperationBinding op = bc.getOperationBinding("ExecuteWithParams3");
        op.getParamsMap().put("param_id", paramId);
        op.execute();
        DCIteratorBinding iter = (DCIteratorBinding)bc.get("Iterator");
        iter.executeQuery();
        Row[] mappedSystems = rowSetItertor.getAllRowsInRange();
        return mappedSystems;
    }The properties for the iterator were Refresh = referred (default) and Cache Results = true. // Nothing
And Refresh = never and Cache Results = false // Nothing.
