Event support for identifying invalid formula before creating the calculated field

The calculated field feature enables end users to create a new calculated field in the pivot table, utilizing available fields from the bound data source or using a basic formula with simple arithmetic operators. However, if a user attempts to create a calculated field with an invalid formula, an error dialog will appear to prevent the execution of an incorrect calculation. Therefore, we need to provide an  event support to detect invalid formulas before a calculated field is created. 

Additionally, if an invalid formula is entered, we should provide an option to suppress the error dialog. Below flow chart explains the proposed implementation, which shows that you need to modify the actionName within the actionComplete event to stop the error dialog from appearing.
