Hello Mirek

Using XmlizeByJsonize() when loading an empty String field I get an exception. See this:

template<> void Jsonize(JsonIO& io, String& var)
{
	if(io.IsLoading()) {
		const Value& v = io.Get();
		if(IsString(v))
			var = v;
		else
			throw JsonizeError("string expected");
	}
	else
		io.Set(var);
}

If v is Null an error is thrown.

A simple solution could be to put:

template<> void Jsonize(JsonIO& io, String& var)
{
	if(io.IsLoading()) {
		const Value& v = io.Get();
		if(IsNull(v))		// NEW
			var = "";	// NEW
		else if(IsString(v))
			var = v;
		else
			throw JsonizeError("string expected");
	}
	else
		io.Set(var);
}

Best regards
Iñaki
