Hi,

I'm having a problem with %JSON.Adaptor and "list of" binding.

For exemple, this class with a property "oazisCode As list of %String".

Class User.ADGroup Extends (%Persistent, %JSON.Adaptor)

{
/// Code interne
Property code As %String;

/// Libellé
Property text As %String(MAXLEN = "");

Property oazisCode As list Of %String;

}

The first time call to %JSONImport works properly

s r = ##class(User.ADGroup).%New()
s json = {"code": "123", "text":"456", "oazisCode": ["1","2"]}
d r.%JSONImport(json)
w r.oazisCode.Size
2

If I call %JSONIMport a second time with another json , the "oazisCode" property is not cleared and new values are added to the list

s json = {"code": "123", "text":"456", "oazisCode": ["4","5"]}
d r.%JSONImport(json)
w r.oazisCode.Size
4

If I try to clear the property by passing an empty array, it does nothing

s json = {"code": "123", "text":"456", "oazisCode": []}
d r.%JSONImport(json)
w r.oazisCode.Size
4

It seems to be a problem with "GenerateImportInternal" from %JSON.Generator class wich never call "Clear" method of Collection properties.

Is there a workaround or something to do to clear a "list of" property ?

Regards
