Cascading Filter is not working.

Hi All,

I am new to Design Studio(may be I'm asking something very silly)

I am trying to create a cascading filter in Design Studio. The data source I am using is eFashion.unx
The objects are State(OBJ_218), City(OBJ_166) and Quantity Sold.

Below are the steps:

1. Drag and drop two Dropdown boxes (DROPDOWN_1 and DROPDOWN_2).

2. Write a script for event "OnStartup" of application.

DROPDOWN_1.setItems(DS_1.getMemberList("OBJ_218",MemberPresentation.INTERNAL_KEY,MemberDisplay.TEXT,20));

DROPDOWN_2.setItems(DS_1.getMemberList("OBJ_166",MemberPresentation.INTERNAL_KEY,MemberDisplay.TEXT,20));

3. Write a script for event "OnSelect" of component DROPDOWN_1

DS_1.setFilter("OBJ_218", DROPDOWN_1.getSelectedValue());

DROPDOWN_2.setItems(DS_1.getMemberList("OBJ_166", MemberPresentation.INTERNAL_KEY, MemberDisplay.TEXT,20));

4.Don't write script for DROPDOWN_2

5.Save and Execute the application.

6. Select any State in DROPDOWN_1

7. Notice that the DRPDOWN_2 shows the entire City of entire State. As per my thinking it should show the Cities corresponding to selected State.

Am I missing something in the script? Any lead will be appreciated.
