Behaviors sometime require read access to /formdata

On 7.8 it shouldn't be necessary to grant the (live|preview)user access to /formdata (cfr. [1])

Some Easy Forms components though (such as [2]) , require access to the data stored under /formdata to determine client behavior and will use the aforementioned user. Therefore it is necessary to grant at least read access to the subtree, else the Easy Forms component will fail...
