Hi,
I am not sure if this question has been answered already but I am facing this issue and have been searching for solution from past few days -
I tried this formula - xdMath:Eval(xdMath:Eval(/my:myFields/my:group1/my:field1, 'concat(., ",")'), "..") to retrieve selcted values of multi select listbox but somehow it does not work.
I have a list box and a hidden text box beneath it, which is promoted to form library.
I need to get selected value of the listbox as comma separated in textbox. Please let me know if anyone has solution for this.
Thanks!
