>
> When saving the model containing some computed columns using functions of
> `timestampdiff` or `timestampadd`, it failed with throwing an exception as
> follows.
> !kylin5.jpeg!
> This happens because
> `ModelSemanticHelper#discardInvalidComputedColumnsForBrokenModel` used the
> `innerExpression` of the computed column other than `expression`. By design,
> the `innerExpression` is used for spark, the expression used by calcite
> parser.
