Valuelist with different types

Hi, is it possible for a Value List to display values with different data types? Currently I can do this but I am seeing an error dialogbox saying that the value list has been set to a data type already. I am reusing my combo box to display date, text, or integer values by customizing the Value List data. How do I disable the warning dailogbox?

Thanks

you shouldn’t do that, just make different valuelist based on what types they have inside them self.
