deserialization problem

[blar58]

I have an error showing the following message :

NinjaTrader.Indicator.xxx could not be deserialized : There is an error in XML Document (1,2038).

If I look at the trace file I don't see anything related to deserialization problem. I looked at all properties and everything seems to be fine there.

Don't know what to do

Where is the XML file so I can take a look at it

Thanks

Hi blar58,

What is the name of the script causing these errors? Do you have a simple version you could share showing the same result so we can give it a run here?

[blar58]

Ryan

This is an indicator developed for customers.

It is not a simple indicator more than 3,500 lines of code.

Hello,

In this case please run through and do the first round of debugging. I suspect that this message is not related to the indicator and the users workspace file is simply corrupted.

In which case a new workspace would resolve the issue let me know if it does not.

If it does not then we would need to see what in the indicator is causing the corruption. Most likely something going on in the Properties of the indicator. Can you send us the property code your using.

This code segment can be sent to support at ninjatrader dot com ATTN: Ryan M with this thread referenced if you do not want to post it.

Thank you for your answer. I cannot test that right now but will do it later. As soon as I can I give you the result.

Thank you

Thanks, I looked through those but nothing stands out. Best recommendation here is to restore your code to a point when you didn't see the error, to isolate exactly what is contributing to it.

When did it last work as you expect? When did you first see this error? Any code that was added in-between those two points in time should be commented or removed.

We're happy to give it a run here as well, but would not be able to offer much unless we're working with only the minimum amount of code that shows the error.

Try putting an [XmlIgnore()] attribute on each of these properties until you find the culprit(s). i.e., on all the properties that are not declared using a primitive type.

Thanks Goganam for your suggestion but I could not found any problems there.

I am just woundering if the problem would not come from here. I have a class named Order in a namespace and I create a new instance of that class in another class inside the NinjaTrader.Indicator namespace.

Here is the code :

namespace Scalping.Service.Model
{
	#region Orders
	
	public class Order 
	{
		public int Id { get; set; }
		public int OrderStatusCode { get; set; }
		public string EntryPrice {get; set; }
		public string StopPrice { get; set; }
		public string TargetPrice { get; set; }
		public string ExitPrice { get; set; }
		
		
		public OrderStatus Status
		{
			get
			{
				return (OrderStatus)this.OrderStatusCode;
			}
			set
			{
				this.OrderStatusCode = (int)value;
			}
		}
		
	}


}

public class RangeClass
		{	
			public RangeClass()
			{
				RngOrder = new Scalping.Service.Model.Order();
				RngOrder.OrderStatusCode=4;
			}
		
			public Scalping.Service.Model.Order RngOrder;

}

Hello,

Could be the case with those parameters in the custom class.

Can you try with a copy of the indicator that does not declare any custom classes to see this resolved.

-Brett

[blar58]

Brett

It could be difficult because I am using these classes all over my 4000 line code.

What would be the best way to serialize and deserialize these class. I have seen a few way but I am a bit lost about which way I should take.


Thanks

[NinjaTrader_Brett]

Hello,

Unfortunately that would be beyond the level of support we could provide. However what I would try is [XMLIgnore()] on your properties of your own classes just to see if this is in fact the issue, or removing the classes out to test.

-Brett

[blar58]

I found my problem

I created another indicator with a new name and copied my indicator.

That's it. Now no more serialization problem...

Solution

That's probably due to the fact that you saved the setting of the indicator as default, then after that you updated your indicator configurations which are different from prior saved as default settings.

All you have to do is to double click the indicator again and again until it's added to the chart, then you right click the setting and "save as default" this will solve the issue.
