//TODO: one reason for this might be a too large binder transaction -> maybe at least give some feedback to the user
//TODO: or somehow scrape sub-nodes first in order to have separate smalle transactions?#
// How to Prevent MAX binder transaction / max parcel overflow, Could happen when getting a list node with many immediate GPG text views (the listnode prefetches its children, and if all of them have a long pgp encoded text, this may just be too much for a single binder transaction)
// size is 1 mb, let's say 50 nodes gives 20 k per node, worst case every character is encoded with 4 bytes gives 5 k text!!! -> might just be enough for pgp
// >hmmm, prefetching descendants works recursively, but will always fetch max. 50 nodes,
// -> hopefully not needed but there's noreal way around it!other than using reflection to get the child node's IDs and then manually doing refresh
