Hello Syncfusion team,

We've recently updated to to be up to date, but we started to have several problemas with some ComboBoxFor that were previously working perfectly.

For example:

@Html.EJS().ComboBoxFor(model => model.UserID).Render() 
is giving us a NullReferenceException. We didn't change anything, just updated your library.

Any suggestions?

Thanks in advance.
