NullReferenceException when trying to set class property

Question

Basically I have 2 classes, \"Manifest\" and \"BrowserAction\", set out like this:

public class BrowserAction
{
    public string default_icon {get; set;}
    pu         


        

Answer 1

change your manifest class to

public class Manifest
{
    public BrowserAction browser_action { get; set; }
    public Manifest()
    {
        browser_action = new BrowserAction();
    }
}

the problem is the property browser_action never initialiazed!
