Cascading filters not working in Design Studio with Universe

Question

Hi,
I am trying to create cascading filters in Design Studio 1.2.
I have one data source
DS_P2 which returns two measures:
(product code)
(investment code)
2 drop down boxes:
PRODUCTCODEDROPDOWN_2 (product code)
DROPDOWN_1 (investment code)
1 crosstab component (to display DS_P2)
Connecting to a BO Universe, Single Connection, relational SQL database
Script On Startup:
//To populate the product dropdown list & Set default value
PRODUCTCODEDROPDOWN_2.setItems(DS_P2.getMemberList("_Rd3rMcNtEeOlu9zFKasaVQ", MemberPresentation.EXTERNAL_KEY, MemberDisplay.TEXT, 50,"All"));
PRODUCTCODEDROPDOWN_2.setSelectedValue("All");
//To populate the Investment dropdown list & set default value
DROPDOWN_1.setItems(DS_P2.getMemberList("_9HY_4cBvEeOMbdZh-4RtVw", MemberPresentation.EXTERNAL_KEY, MemberDisplay.TEXT, 50, "All"));
DROPDOWN_1.setSelectedValue("All");
"On Select" script for PRODUCTCODEDROPDOWN
//Filter data set P2
DS_P2.setFilterExt("_Rd3rMcNtEeOlu9zFKasaVQ", PRODUCTCODEDROPDOWN_2.getSelectedValue());
//Re-populate the Investment dropdown list & set default value
DROPDOWN_1.setItems(DS_P2.getMemberList("_9HY_4cBvEeOMbdZh-4RtVw", MemberPresentation.EXTERNAL_KEY, MemberDisplay.TEXT, 50, "All"));
DROPDOWN_1.setSelectedValue("All");
The image below shows that the second dropdown box is not filtering correctly based upon the selection made in the first drop down box, the second box should display list, E_CASHUP, E_GWROTH, E_STABLE, S_GROW_ACT,ZZZZZZ, P_BAL_IDX
Does any one know if there is a limitation to creating a cascading filter when using universes?
Am I doing something wrong?
ARRRGGGHHH any help appreciated

Penny,
You can try using SDK to achieve your goal.
I posted once a ComboBox example, i know it does not do what you want right now, but it could be a starting point.
ComboBox with custom items
Mike also has some great examples here.
