We use the node label parameter plugin to pass the name of the node selected to another plugin "Active Choices Plugin" that's replying on UI elements change, but when I use ${NODE_NAME} as reference parameters, it didn't work, looks like it didn't response the value selected from Node drop down list. ${NODE_NAME} is empty before build, the value filled until it start to build. I can find ${NODE_NAME} in environment variable. is it possible to auto response the value of drop down list dynamically? or am I using wrong UI element as reference parameters, but I did try with name "nodes" of Node definition. it didn't work neither.

BTW, I was using "Disallow multi node selection when triggering build manually" to get single DDL.
