How to create drilldown bar graph using clicklistener

Question

Hi,
I have a view object that sums some data and tags each sum accordingly - eg sum salary grouped by department name.
I display this using a horizontal bar graph.
I want to now be able to click on a bar and then have the details displayed in a table. I am led to believe from chapter 24 of the manual it is possible to do using no java coding (ie not having to create a bean etc).
You can use the row selection listener of a graph (which serves as a master view) to enable clicks on a bar, slice, or other graph data element to update the data in another ADF component (which serves as a detail view). For example, a click on a bar that represents sales for a given product in a graph might cause the display of the detailed sales data related to the product in a pivot table.
The following requirements must be met to achieve this master-detail processing declaratively:
1. You must use the same tree data control to provide data for both views as follows:
1. Bind the graph as a row set to one level in the data control.
HOW ?
2. Bind the other ADF view (such as a table or pivot table) to a lower level in the tree data control.
I don't have a nested iterator - is it saying to use a master-detail scenario like dept/emp ?
2.
Set a value for the clickListener attribute of the graph tag in the Behavior page of the Property Inspector and use the processClick method that is already part of the graph binding.
For example, if the value attribute of the graph tag is value="#{bindings.myGraph.graphModel}", then the clickListener attribute should be clickListener="#{bindings.myGraph.graphModel.processClick}".
3. Ensure that the partialTriggers attribute on the parent tag for the detail component is set correctly. It should be set to the ID of the graph component.
You do not have to write Java code for handling clicks on data elements in the graph. The processClick event on the graph binding recognizes click events on data component in a graph and performs the necessary processing.
Are they suggesting all you need to do is ensure you have proper master-detail tables set up and it will automatically work ?
cheers

Hi Frank,
thanks for replying. I opened a TAR about this as I cannot produce a drilldown table. I created a VO with my summary - eg
select decode(manager_id, 100, 'fred',
123, 'bill', 120, 'kate', 121, 'julia', 147, 'ken', 108, 'james', 148, 'liz',
149, 'phil', 205, 'jack', 102, 'eric', 'dominic') manager_name, sum(salary) as salaries
from employees
GROUP BY
decode(manager_id, 100, 'fred',
123, 'bill', 120, 'kate', 121, 'julia', 147, 'ken', 108, 'james', 148, 'liz',
149, 'phil', 205, 'jack', 102, 'eric', 'dominic')
Then I created a detail view object (from HR.employees) and added a calculated column :
SELECT Employees.EMPLOYEE_ID,
Employees.FIRST_NAME,
Employees.LAST_NAME,
Employees.EMAIL,
Employees.PHONE_NUMBER,
Employees.HIRE_DATE,
Employees.JOB_ID,
Employees.SALARY,
Employees.COMMISSION_PCT,
Employees.MANAGER_ID,
Employees.DEPARTMENT_ID,
decode(manager_id, 100, 'fred',
123, 'bill', 120, 'kate', 121, 'julia', 147, 'ken', 108, 'james', 148, 'liz',
149, 'phil', 205, 'jack', 102, 'eric', 'dominic') AS manager_name
FROM EMPLOYEES Employees
I create a new viewlink which links on manager_name. When I run the bc4j appmodule I can see the correct master-detail relationship. IF I drag a master-detail table onto the page it works fine.
Now if I create a graph using the master and then create a table using the detail I can't get it to use this relationship even after setting the processClick() and the id for the graph set on the partial trigger of the table. Any ideas ?
cheers
