Erroy by saving a MA-Template

[TheChingachgook]

The following error is written into the tracefile when I try to save
a MarketAnalyzer Template.

with the following column: NinjaTrader.MarketAnalyzer.TradeEscort

this is a self coded description column

The strange thing is, that I have done that already by 100times with the same component and suddenly I'm getting this error

does anyone know the problem?

.....

By opening the MarketAnalyzer this Column is also missing.
In the trace file I also found the following error:

2009-12-20 16:04:45:828 ERROR: Failed to restore Market Analyzer column 'NinjaTrader.MarketAnalyzer.TradeEscort'. Most likely (a) the implementation changed or (b) one or more properties have been renamed or removed or (c) the custom assembly which implements this indicator no longer is there.


... When I add this column in the MarketAnalyzer it works fine - storing the template or storing the workspace causes the problem again.

But I'm using this column already since month's an I never had problems.

Hello,

I am sorry, the custom coded part is beyond our level of support.

Hi Ben

I don't understand your answer ...
what is the difference to a custom coded indicator or strategy ?

I only would need a hint what this error message means and how I can fix it.

I'm in the process to become a NinjaTrader partner with a 3rd-party add on within the next weeks and this error would prevent this intention and this solution is a bit more complex than a solution for privat use only.

So I really would be happy if you could help me.

many thanks for your cooperation

Hello,

What do you mean by custom coded the description column. I've never heard of someone doing that so I suspect that this is beyond my personal level of understanding. I will have someone take a look at this on Monday. Sorry, I just don't know the answer because I haven't been train this aspect...because its beyond our level of support for normal users.

Hi Ben

I've found the problem.

With a DescriptionColumn I meant a self coded MarketAnalyzer-Column. This term I've found somewhere in the forum and therefore thought it's in common understanding of the support members ... sorry for that confusion.


The solution is, that the XmlReflectionImporter.ImportTypeMapping has a problem by passing an object into a constructor, but the compiler and the executable don't regconize a problem with that. So it seems the ReflectionImporter cannot dissolve the API when an object is passed into the constructor.

Thanks for your good will
