Using groovy expressions to get a value of the current row

Question

Hi,
I have a bounded task flow. The first step in the flow is calling an ExecuteWithParameters on one of my views. Based on the result of this query, I want to go to either Page1 or Page2.
So I have a router. I first tried to route based on whether or not the result of the query contained only one row. That worked fine. But I want to add a condition to that.
Basically, if the query returns one row AND that row has an attribute named 'Noc' == 1, then I want to go to Page2. Otherwise, go to Page 1.
Right now to get the estimatedRowCount I am getting the iterator from the pageDef file created for my ExecuteWithParams object. To see if 'Noc' == 1, I tried this:
#{data.rcl_view_reimbCode_search_results_task_flow_reimbCode_search_results_task_flow_ExecuteWithParamsPageDef.ReimbCodeSearchView1Iterator.currentRow.getAttribute("Noc") == 1}
But it is complaining of grammar issues.
What is the best way to go about getting the value of my attribute in a groovy expression?
Thanks,
Joel

Hi,
the best way is to use a managed bean reference
1. create a binding for the router
2. Expose the queried iterator in the PageDef file
3. write a managed bean that accesses the binding
BindingContext bctx = BindingContext.getCurrent();
BindingContainer bindings = bctx.getCurrentEntry();
DCIteratorBinding iter = bindings.get("NameOfIterator");
// i) get estimated row count
// ii) get attribute value
//iii) evaluate
// iv) return true/false
Reference the managed bean from the router
