Smart Markers using generic List as nested objects

When using a generic list of type ExpandoObject as the datasource for a nested object, then the smart markers arent processed correctly.

Is it supported to use a List < dynamic > as the datasource for a nested object?
Because now all i get as output inside the Excel is: System.Dynamic.ExpandoObject


Could you please share sample code snippet (runnable) and sample Excel file(s) to show the issue, we will check it soon.

Thanks for the samples.

Please notice, I am able to reproduce the issue as you mentioned by using your template file. It looks like it is not supported to use List (of type System.Dynamic.ExpandoObject) as the data source for a nested object. But we need to evaluate it thoroughly. I have logged a ticket with an id “CELLSNET-50776” for your issue. We will look into it soon.

Once we have an update on it, we will let you know.
