A snippet of my code is below. My problem is that the ResultVaueSetter's 'field' value (in this case the value of 'leaf') is printed by downstream modules (in this case by the table chosen by Switcher) and I cannot find a way of stopping this behavior. Any help is appreciated !
Short Answer: Give the Switcher module group=" ". There's a bullet on the first Switcher docs page, that says this but it's easy to miss.
Long Answer: Switcher module relies on the group attributes even though these attributes have meaning in certain legacy Splunksystems. What's happening here is that the dashboard template is seeing the group attribute values and interpreting them as panel headers. To make this go away you just have to put that weird space character group=" " onto the Switcher and it'll go away.
