Questions regarding "using of Hierarchies in Dropdown Box"

Hi ,

I have a Dashboard created with Design Studio 1.2

I am using a Dopdonwbox filed with two Hierarchies.

Hierarchie 1 = "Blue Cars"

Hierarchy 2 = "Red Cars"

it is working fine if I have only two hierachies.

But if I want to add a third one it is not longer working

Does someone know if there is a restriction or a limit regarding using Hierarchies in Dropdownboxes?

This is my code from the Hierarchy Dropdown:

INFORMATION: APPCOMP" is the Dimension form my Dimeonson-Filter.

OnClick event of the Hierarchy Dropdown Box:

if (HIERARCHY_DROPDOWN.getSelectedValue() == '1') {

DS_BY_PRIORITY_TAB.clearFilter("APPCOMP");
  DS_1.assignHierarchy("APPCOMP", "Hier_BLUE_CARS");
  DS_BY_PRIORITY_TAB.assignHierarchy("APPCOMP", "Hier_BLUE_CARS");
}
   if (HIERARCHY_DROPDOWN.getSelectedValue() == '2'){
  DS_BY_PRIORITY_TAB.clearFilter("APPCOMP");
  DS_1.assignHierarchy("APPCOMP", "Hier_RED_CARS");
  DS_BY_PRIORITY_TAB.assignHierarchy("APPCOMP", "Hier_RED_CARS");
}
   if (HIERARCHY_DROPDOWN.getSelectedValue() == '3'){
  DS_BY_PRIORITY_TAB.clearFilter("APPCOMP");
  DS_1.assignHierarchy("APPCOMP", "Hier_GREEN_CARS");
  DS_BY_PRIORITY_TAB.assignHierarchy("APPCOMP", "Hier_GREEN_CARS");

}
