Error message in log

[photog53]

Platform NT 7.0.0.20

I just noticed an error message that shows up in my log.

"Failed to call method 'Initialize' for indicator 'PASwh2':
Object reference not set to an instance of an object.

Everything seems to work OK....I only noticed this by accident when I was
nosing around in the log. The indicator in question (PASwh2) works fine.

My question is.........
What might be causing this error???
Is the error something I should correct???

Thanks..........

photog53, this error could be caused by many, many different coding "errors". It usually occurs when you try to access some object without checking to see if it is null. If you post the code we can help narrow it down.

Thanks for the quick reply.....

I'll attach the code....

(This indicator is based on the standard Ninja ZigZag....I added code to it)

photog53, unfortunately nothing stands out in the Initialize() section that could be causing that error. You will have to wrap each section in try-catch blocks to see where exactly the error is coming from.

try
{
    // do anything here, like access an array or something
}
catch (Exception ex)
{
   Print("exception in init() for modified zig-zag at line [insert some line number reference here]: " + ex.ToString());
}

Thanks......

(I don't feel so dumb now...because I didn't see anything obvious either)....

I think I found the problem.....

After some trial-and-error....I figured out the problem.

I had the following code in .....

protected override void Initialize()
{
( other initialize code......)

if (ChartControl.BackColor == Color.Black)
targetBorder = Color.White;
else
targetBorder = Color.Black;

I removed it and the log errors stopped.....

It appears that I NT7 does not like using this code in initialize....

Glad you figured it out, this is correct - did you move it to OnStartUp() instead?

[photog53]

I just commented it out for now....but OnStartUp is a good idea

Thanks.....
