blending mode not working correctly when using parameter

I am trying to leverage graph/node input  paramter to control the blending mode of blend node. Seems it cannot work, looks like all value above 0 is treated as 0, so it's always the defalut "Copy" mode. 

 

Here's the version information

      The issue seems to stem from using the value processor as the input to the blend node. Using a normal 'input' node works as expected.

       

      Note however, even if you use an input node, when you come to publish the graph the blend mode will not work as an exposed parameter. It is a 'static parameter' which is fixed when the graph is cooked (i.e. when it is edited or published).

      The way around that is to use multiple blend nodes and switch between them using switch/multi switch nodes
