In Create table dialog box,in Basic Information tab i entered the information and clicked submit button.The message tab is opened with the query and message "The command executed successfully." but Submit button is present in this messages tab.When I click "submit" button it reports an error-"Error occurred while executing the query"
I've noticed this too. However, I don't think it's an "error", per se, just a bit of workflow confusion.
Suggestion: On the "Messages" tab, maybe only after success, either change the "Submit" button to that of "close" (upper right "x") or remove the "Submit" button completely.
