Creating Database Fails when a column has a boolean field, 'Has Default Value' is selected, but 'Default Value' textbox is null

[mvulcano-ptc]

When trying to create a database table, if when adding a column, the 'Has Default Value' checkbox is true, but the 'Default Value' textbox is null, the table create service fails.

In addition, the Composer-side pieces are created, but the database table is not. This requires manually cleaning up the Composer-side entities that are generated.

Expected Behavior: The popup should disable the 'Add Column' button in the UI if 'Has Default Value' is true, and 'Default Value' textbox is null.
