In fpicker module we don't treat template listbox "LISTBOX_TEMPLATE" element
selected in "impl_sta_GetControlValue" function. In order to fix this issue
we added a sequence "gitems" which save items added in template listbox
while creating the ODM creation graphic interface. Also we added a section
in impl_sta_GetControlValue function to get user selection from template
listbox and the get the item from gitems and we return
the value.
