getAllUnchecked returns zero as first item in list

I only see this from getAllUnchecked.

GetAllChecked returns a string delimited with the char specified from the same list.
checkedItems: widget/mashup-root/CloseIfPopup/,widget/mashup-root/Refresh/,widget/mashup-root/ResetInputsToDefaultValue/

unchecked: 0,widget/mashup-root/Refresh/,widget/mashup-root/ResetInputsToDefaultValue/

if no items are checked, I get “0” returned. typeof shows it is a String:
unchecked: 0

I recently upgraded to the latest version of DHX library from an older version that never had this issue.

Any suggestions welcome - for now I have to check for and shift the zero as it breaks my app!
