Invalid class typecast for property "x" [Expected: TArray<System.string>, Actual: Array]

[AlbertSchimidt]

Hello again!

I've been using DMVC for a little long time now, and it works great.

But now I'm having trouble with TArray class. Like in the sample "renders" provided from the samples.zip, I can SERIALIZE an TArray<System.string> just fine, but I cannot seem to DESERIALIZE an json array. Always getting the same error "Invalid class typecast for property "x" [Expected: TArray<System.string>, Actual: Array]".

My json array is like this:

{
    "myProp": [
        "Test1",
        "Test2"
    ]
}

It's the same array generated by the Render method.

My class is like this:

TMyClass = class
private
  FMyProp: TArray<string>;
public
  property myProp: TArray<string> read FMyProp write FMyProp
end;

Trying to DESERIALIZE like this:

var
  oMyClass: TMyClass;
oMyClass := Context.Request.BodyAs<TMyClass>; // raises "Invalid class typecast for property "x" [Expected: TArray<System.string>, Actual: Array]" error

What I'm doing wrong?
