discoveryFunction selection

> That won't work, you can access contexts by string but you can't create them that way, that requires actual Java class objects.
Thank you, that hint already helped me

for list reference to close that thread: creation of a ScratchContext below PRC in a ContextFunction:
scratchCtx=new org.opensaml.messaging.context.ScratchContext();
input.addSubcontext(scratchCtx);
scratchCtx.getMap().put("selectedIDP",event.toString());

that’s then accessible in discoveryFunction as well.

I fully understand. Actually, a membership is already budgeted starting from 2024.
