i want to transfer a attriute and make sure that after several frames i will have it. trying the tutorial

but nothing moves inside the solver

how can i use the solver to keep the attibute?

I think your inputs are mixed. Swapping them works.

yep very interesting, but if i invert and want the ball to be the one keeping the attribute.... caput... doesn't like that. like "Prev_Frame" node doesn't actually moves,

Oh yes if you want that you have to copy all attributes except P from previous frame node like this and then do the attrib transfer after:

It's a custom Python Qt extension that I explain here around (30 mins mark):
