Hello Mirek

Running this sample a "invalid Value type" exception is thrown:

xmldemo.cpp

#include <Core/Core.h>

using namespace Upp;

struct MyClass {
	Value val;
	void Xmlize(XmlIO& xml) {
		xml
			("Val", val);
	}
};

CONSOLE_APP_MAIN
{
	MyClass demo;
	
	String fileName = AppendFileName(GetDesktopFolder(), "demo.xml");
	
	try {
		LoadFromXMLFile(demo, fileName);
	} catch (XmlError error) {
		Cout() << "\nError: " << error;		
	}
	ReadStdIn();
}

demo.xml

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!DOCTYPE Demo>
<Demo>
</Demo>

A possible but ugly solution is to remove lines 405-406 in Value.cpp:

	if(Upp::IsNull(type))
		throw XmlError("invalid Value type");

In addition it would be great if LoadFromXML() would throw the exception to let the program to handle the errors, like this:

	catch(XmlError error) {
		throw error;
	}

Now the XmlErrors do not arrive to the program as LoadFromXML() catch them but do not re-throw them.

Best regards
Iñaki
