My original code is the next one:
first the collection with modified data

then, the data source, (which are the same)

They have the same data and IDs aswell
ColeccionGuardarA2

ColeccionDataSourceA2

Okay now im showing the forall with the patch statement which is not working:

if i change each field for a static value, for example Regulacion: "AAAAAA" it also doesn't work
