Martin,
I tried the filter and the filter runs quite well but no change on the
tag... Everything remains the same.
Do you see something wrong? It also runs several times, not just one.
One for each component that has body in it's html. I suppose that is
normal Right? But how to know which one is the one that is going to be
rendered? The others are discarded...
Thank you.
