Market Analyzer broken after saving Workspace

[saltminer]

Hi,
i have written a Market Analyzer column which works fine - until the workspace is saved. After that the Market Analyzer cannot be edited, giving the error visible in the screenshot below. If Ninja is restarted, the Market Analyzer is blank/empty.
I know that when an indicator has an xml issue, saving the workspace will create a log error message, however in this case no error appears in the log tab when saving.
I've triple-checked the public Properties and all seems fine. I'm baffled. Assistance will be appreciated.

Cheers,
saltminer

UPDATE:
I've tracked the problem to this Property, but I don't know what's wrong with it. It compiles, it produces results. It just won't save in the Workspace without killing the Market Analyzer. (silently)


[NinjaScriptProperty]
[Display(ResourceType = typeof(Custom.Resource), Name="SMAXCON Fast MA Type", Order=922, GroupName="PriceExpansion")]
public NinjaTrader.SMAXCONSpace.MovAvgType PriceExpansion_FastMAType
{ get; set; }


This is in an indicator, where it is declared like this:


namespace NinjaTrader.SMAXCONSpace
{
public enum MovAvgType
{
SMA,
EMA
}
}

#region NinjaScript generated code. Neither change nor remove.
.... etc

Hello saltminer,

That may relate to where the enum is defined in the script. As an example indicators need to define the enum in a specific location in contrast to the indicator class, that may also hold true for analyzer columns. You could first try moving the enum to a similar structure as shown in the following sample in the link. Its also possible that the error comes if you are not setting a default value for that property from State.SetDefaults.

If that does not work you may need to use a secondary serialization property here.
