but I get the compiler error:

Does anyone know what I am doing wrong? Or is there is a better way to do
this? I'm sure this is a dumb question, but I couldn't find anything in the
tutorials/examples.
You've already solved this one problem by converting the ArrayView to a
std::vector by hand in your next mail.

That's more complicated. The exception happens in the line
iter->set_properties(...)
and tells you that the particle 'iter' points to isn't associated with a
PropertyPool, i.e., the object that stores particle properties. I'm not sure
why that is so. I believe that from your code, you set up the ParticleHandler
to hold properties, but I can't see where the ParticleHandler's PropertyPool
would be propagated to the newly added particles.
Can you create a minimal program that shows the issue? It doesn't have to do
anything useful, just illustrate the error.
