Pass multiple values to a prompt in Design Stduio

Hi,

I have a design studio dashboard based on a universe. There is a listbox filter in the dashboard. The users can select single or multiple values from the listbox. We need to pass those values to a prompt in one of the data sources.

It works fine when users select single value from the Listbox, but doesn't work for multiple selections.

Here is the code for passing single value.

APPLICATION.setVariableValue("pmEnterCompanyCode", LISTBOX_COMPANY_CODE.getSelectedValue());

It doesn't accept LISTBOX_COMPANY_CODE.getSelectedValues() for multi value selection.

We are on Design Studio 1.2.

Any suggestion or work aorund for this requirement?

Thanks in advance for your response.

Regards
