Are you using property level validation or Page level Validaiton. Property level validation will show the error in the property frame. Try using Page level validation and check.
You can also a custom layout to log the error message anywhere in the screen if required based on some flag or property etc
@Thenuzan - In table cell we will be seeing the validation message only with red color warning symbol on the top of the cell. On hover of that icon will be seeing the error message. This is the expected behavior when the control is inside the table.
