How to Convert ListTextValue into String?

Hi,

I am wondering, if there is an elegant way to read the content of a java script variable of type  „ListTextValue“ containing only one entry.

My scenario: I get the MemberList of a dimension with only one entry. To read this entry as per now I have to fill a dropdown Box and read the text of the first entry.

Is there a direct way to read the name?

Thanks in advance,

Julian
