# Introduction
After updating a `viewField` in a view the frontend receives a missmatch
metadata version.
That's because the `flatFieldMetadata` needs to be invalidated on a
viewField addition as it contains its primary key in its cache.
Before we would be checking updated flat entity maps, meaning that on a
view field update the flat field metadata maps would also get updated,
but we also invalidate the old v1 cache at the same time. Resuling in a
metadata version missmatch that's not really relevant for the gql schema
integrity
Now we only check if a object or field actions has been processed, if
yes increment the metadata version.
We should deco-relate the v1 object and fields cache from the metadata
version that should only serve as a "Please refresh browser state
because gql schema has mutated"
