OBIEE - Using Multiple Select Rows In Grid As Parameters

Question

Hello All,
First post from an OBI Newbie. I am getting used to creating dashboards and have got my head around drilling with values, but I have a user requirement that I am not sure is possible.
A standard query returns the following datagrid information ("," = column divider):
Product Id, Product Description, Colour, Total Sales
1, Chair, Red, 4
2, Chair, Blue, 3
3, Chair, Black, 5
I know that I can enable a drill on a specific colour to give a datagrid such as (if Red Selected):
Order Reference, Product Id, Product Description, Colour, Units
687678657, 1, Chair, Red, 3
687678658, 1, Chair, Red, 1
The user requirement is to select multiple rows (possible by holding Ctrl) and to then effectively "drill" with the multiple selected values. Eg Red, Blue:
Order Reference, Product Id, Product Description, Colour, Units
687678657, 1, Chair, Red, 3
687678658, 1, Chair, Red, 1
687678660, 2, Chair, Blue, 3
I presume that a separate report will be required, but I am not sure how to trigger and/or pass the multiple product id's. Can anyone help with a solution?

I got this working by changing the signature of the Application Module method to use ArrayList rather than String[], then you can marshal the Struts FormBean contents into an ArrayList to pass up.
To do this, subclass the DataAction by using "Go To Code" off of the context menu and then override the initializeMethodParameters() method:
  protected void initializeMethodParameters(DataActionContext actionContext, JUCtrlActionBinding actionBinding)
    //Get the String Array from the Form Bean
    String[] selection = (String[])((DynaActionForm)actionContext.getActionForm()).get("multiSelect");
    //convert that to an ArrayList
    ArrayList selectionArr = new ArrayList( Arrays.asList(selection));
    //Add that object to the Arg List for the AM method
    ArrayList params = new ArrayList();
    params.add(selectionArr);
    actionBinding.setParams(params);
  }
