NT8.0.0.7 File Import Issue when DashStyleHelper type used in Input

[engrvivs]

Hi

I'm using a DashStyleHelper type variable as part of inputs in a custom indicator. This input allows one to change line style. For this following is performed:

a. in OnStateChange(), within if (State == State.SetDefaults):
ils_ExtendLineStyle = DashStyleHelper.Solid;

b. in #region Properties:
[NinjaScriptProperty]
[Display(Name="Line Style", Description="Style of extended horizontal line", Order=3, GroupName="Extended Line Properties")]
public DashStyleHelper ils_ExtendLineStyle
{ get; set; }

c. Lastly I include DashStyleHelper ils_ExtendLineStyle as part of parameters in functions inside #region NinjaScript generated code, like:
NT8_Indi NT8Indi(bool onAlert, DashStyleHelper ils_ExtendLineStyle, int ii_PriceTextSize)
etc.

The code executes and operates without errors.

However, when I export the NinjaScript file as compiled assembly, it can't be imported back to the system. Import displays following message:
"Import Failed. The Ninjascript Archive file may contain duplicate method names that already exist on your PC or there is a required file missing on either your PC or in the input archive."

Through certain hit and trials, I observed that removing DashStyleHelper type input or changing the variable's datatype allows successful importing of .zip file.

May someone point out how this issue be resolved while using DashStyleHelper type input.

Thanks

Hello engrvivs,

Thank you for your post.

Can you attach or send us (at platformsupport[at]ninjatrader[dot]com) the .zip file you attempt to import?

Thanks Patrick for response!

PFA the .zip (and the .cs) file(s) which is exhibiting error on being imported.

Thanks
Vivek

It is exactly as it says. You are trying to import a file while the source already exists in the file tree. Ergo, duplicate methods. You cannot import an exported file into the source tree.

Thanks koganam for the response!

Yes, I agree that while the code is in the compilation tree, the .zip file can't be imported. Thus, what I generally do is to "Exclude from Compilation" the file in NinjaScript Editor. Thereafter, I import that file thru .zip.

As I mentioned earlier, such method of importing works for all cases, except when I'm having a DashStyleHelper type among input parameters.

Thanks

Hello Vivek,

koganam is correct. As you have exported the files they still exist in the installation and importing the exported files creates duplicates and thus conflicts and errors.

Hi Patrick

So, does this means you were able to successfully import the NT8p0p0p7_ImportIssue_Indi.zip file at your end?

Kind Regards

Hello engrvivs,

Can you send the source files that are exported? My import fails, but when I manually import and add the reference I see that the DashStyleHelper could not be found - askign if I am missing an assembly or reference.

Thanks Patrick for checking the import failure at your end.

The source code was also attached earlier as NT8p0p0p7_ImportIssue_Indi.cs file.
Please find it attached with current message too.

Specifically look for the input variable ils_ExtendLineStyle within the code, which is causing the issue. The importing issue occurs with that .zip, which is exported "as compiled assembly".

Thanks for your valuable time.
Kind Regards

Hello engrvivs,

I am seeing the exact same issue with any indicator I export into an assembly that calls an enum from NinjaTrader.Gui. I am checking with development on this item.

Thanks Patrick for recognizing and generalizing the issue!

Hello Vivek,

Thank you for your patience.

At the moment the only way around this is via a direct call. For example:

public [B]NinjaTrader.Gui.DashStyleHelper[/B] dash
{ get; set;}
