CS1518 while porting indicator from Ninja 7 to 8

[sgkcfc]

Hi

my previous NInja 7 code was something like this

#region Properties

[Description("balh")]
[GridCategory("Parameters")]
public int Aggression
{
get { return aggression; }
set { aggression = Math.Max(1, Math.Min(3,value)); }
}

It doesnt compile in Ninja 8 like that.

So i changed it to

[Range(1, 3)]
[NinjaScriptProperty]
[Display(Name="Aggression", Description="Blah", Order=1, GroupName="Parameters")]
public int aggression
{ get; set; }

i still get that error. This is common with almost all the properties defined in the indicator. Would appriciate any help.
Thanks!

Hello sgkcfc,

The range is between 1 and 3. Do you have a default value of 1 being assigned in State.DataLoaded?

You have mentioned: "i still get that error. ". What is the error message you are getting? On what line is there? What is the code on that line?
