Jsonize problem with Null [message #36166]

Hello Mirek

This problem launches a NEVER() in ValueType:

Vector<Value> a, b;
a.Add();
String json = StoreAsJson(a);
LoadFromJson(b, json);

json String is set to "[null]".

It seems that while StoreAsJson() can save Vectors with Nulls, LoadFromJson() is reluctant to them.

Best regards

Weird, tried, unable to reproduce (in Linux 64 bit). And I do not even see the reason in the code.

What is your setup?

Sorry Mirek. What does "setup" means?

MSC9, WinXP.

It is true. In Linux 32 bits it does not launches a NEVER().

Tested with MSC, Win 7, still not reproduced. Are any other setup traits involved?

Can you please try with upptst/JSON? If it passes, you can alternatively try to create your own test package and submit to upptst? Or perhaps just add another test to upptst/JSON...

Hello Mirek

The problem appears compiling with GUI but not in CONSOLE.

I have tried to debug the same code in both manners and the difference is in Value::GetType("") when calling
