Serializaton Error

[dontpanic]

Hi,

I'm getting the below serialization error when I try to save my workspace, but I can't figure out from that error what it is in my indicator that is causing the error. My indicator has a windows form in it, I'm guessing its got something to do with that, but is there any way to track down more accurately what the cause might be?

Thanks,
Will.

Hello dontpanic,

Thank you for your post.

Serialization errors can occur when a property has not been serialized, this is common in colors that are user defined variables. You can find information on serializing colors at the following link: http://www.ninjatrader.com/support/f...ead.php?t=4977

For the error CS0272, which is also in relation to properties, please visit the following link: http://msdn.microsoft.com/en-us/libr...(v=vs.90).aspx

Thanks,
I was able to find the offending protected set and remove it. The code that was causing it isn't mine, I borrowed it, so I'm not 100% sure what effect the change will have. Is it possible to tell NT not to serialize that variable, as an alternative fix?

Thanks,
Will.

Hi Will, we're glad to hear that. Would suggest to look into the XmlIgnore attribute - http://msdn.microsoft.com/en-us/libr...(v=vs.90).aspx

Thanks, XmlIgnore did the trick.
