[leshan-dev] Integer resource with no value

[Bill Bennett <william.bennett@xxxxxxxxxxxxxxxxxxx>]

Hi,

What do you think is correct behaviour for an integer resource with no 
value?

At the moment my client returns it as an empty string, which generates 
an error in Leshan: "500 [Invalid value for integer resource: ] ([/7/0/2])"
This example is happening because the interface is not connected, so 
there are no statistics yet (but there will be later).
Is Leshan right to display an error, or should it accept it and display 
a blank?

I don't think returning "0" is always right (though this example would 
be OK). Also 4.04 Not Found implies that the resource doesn't exist at all.

Cheers,
Bill
