TS API GetValVariant with custom data type causing error

[bigyo]

Hello All,

I'm using TS2017 SP1, I want to make a ProjectConfig configuration entry point in the process model, which reads the values of a FileGlobal of a client sequence in editmode, and returns it after modification to the client sequence file.

The config parameter is a custom data type.

I get the reference of the client FileGlobals, and I managed to use the SetValVariable function, which writes the custom parameter to the client sequence without issues, but reading the values with the GetValVariant is causing and error: "-17308; Specified value does not have the expected type."

But the types are equivalent in both sequences.

Is this behavior known? Is there any workaround possible?

Thank you in advance.

Hi bigyo,

I see your post wasn't touched for quite some time, do you still experience -17308 error when using GetValVariant?

If you found a solution, could you share it with a community?

If you still experience the error, could you share a sequence file, where we could see the error happening?

Thanks.

Regards,

Hello Ajskrim,

The solution was  provided with the help of NI specialist.

When getting the reference of the client FileGlobals, I needed to create a clone of this reference, so I can use the GetValVariant function to work locally on that object.

With that little tweak it is working perferctly.
