Commented Unassigned: nfjsonread breaks when an empty kv is passed [43497]

Hi,

when we pass an empty key-valye collection to nfjsoncreate I get an error. The input data is similar to this:

```
"nfjson_kv_collection" : {
"collectionitems" : [ ]
}
```

The error rises in function reviveCollection at line

```
For T = 1 To Alen(m.tv.collectionItems)

If m.keyValColl
esteval = m.tv.collectionItems(m.T).Value
```

Looks like collectionItems has a not-zero size even if it's empty

Hi,

To create a empty collection from Json, use "<collectionName>_kl_collection" instead of "<collectionName>_kv_collection" ( _kl_collection = keyLess collection / _kv_collection = keyValue collection ) like: { "myEmptyCollection_kl_collection": { "collectionitems": [] }}

This is due to the fact that Vfp collection class has no property to indicate if it's key or keyless; ( "The first item added determines the behavior for the collection" )

check it by doing:
o = CREATEOBJECT('collection')
? nfjsoncreate(m.o,.f.,.f.,'myEmptyCollection')
&& {"myEmptyCollection_kl_collection": { "collectionitems": [ ] } }
