Issue with Combo Box while setting it to null

Content

Hi All

We have seen that with combo box, if we set the field value to null using back space or delete the value then sometime it is setting the value of the underlying field to 0 if the field is of type number. To resolve this I had to change the field type to string.

Let me know if any possible solution on how to handle this so that we can use the combo box with number type of fields.
