When modifying a table's structure, if I accidentally hit the "new" button twice, I end up with two blank columns in the list of columns. I can then enter the information for both columns. It doesn't complain and it appears that all is well. But when I go to save, I get a broken rule, saying the name of the column can't contain spaces. I get this on EVERY column and can't save at all. I must exit without saving and then reenter any thing lost.



To Reproduce

1. In DDT, add a new table

2. Add a column and define it

3. Add another column and define it

4. Hit the new button twice...not two blank lines in list of columns

5. Enter information in these two columns, including name, no spaces

6. Try to save, I get a Broken rule on name

7. Delete that column and try to save again...get broken rule on another column
