Trying to insert new column: ""Unexpected error" when click "Finish" button without selecting a column type in the box
The popup error appear.
I think user should "guided" through UI to and it should not possible for him to execute "illegal" action. In that situation, the issue is that the user must select a type before clicking finish; but if the user does not knows the tool, seeing the "Finish" button enabled, expects that clicking such button would lead to column creation; so the "error" is that the button should be disable until the user select a column type
