Setting an empty list remove the attributs

[Chique80]

When you use the NMF API to set an attribut that has a cardinality greater than 1 (a list), if you give an empty list, the attribut is instead remove from the node.

On :neo4j-io module, this feature works as expected, even with empty lists. Could you please provide a code example as well as your model?

I think the issue is with the generated code. For exemple, this is the generated setter for an attribute that is a list of strings.

overrive fun setKeywords(v: List<String>?) {
    when {
        v == null || v.isEmpty() -> removeProperty("keywords")
        v.size in 0..3 -> putProperty("keywords", v)
        else -> throw Exception("bound limits: list size must be in 0..3")
    }
}
