[Academy] 9.2 Sort Columns in a List

Hi sandeep,

I can foresee two potential situations that lead to this error:

1. Check the Aggregate and make sure on the dynamic sort you are using the List_SortColumn_GetOrderBy function and that the syntax for the default order, the second parameter, is using curly and square brackets as explained on the video, e.g. {Issue}.[Id].
2. Check the value of the Column parameter of each the List_SortColumn WebBlock and make sure you are also respecting this syntax.

Finally publish your application, close the browser and test again. Why close the browser? The value for of the order by is actually stored in a session variable so that it is kept between page navigations. If you have stored there an invalid value even if you have fixed it in the code you will still have an error in the application. Closing the browser and opening it again ensures that you have a new session and therefore the invalid value is not stored anymore.

Cheers
