> The Flask flash messages are not categorized properly (ref: []
Then the default category would be 'message'. Flask AppBuilder would assign CSS class `alert-[category]`
to that message when displaying it (ref: []
). But 'alert-message' is not specified in *bootstrap-theme.css*. This makes the the flash
messages in the _*www_rbac*_ UI come with no background color (please check the screenshots
attached. We don't see this issue in _*www*_ UI as all flash messages without categories are
classed into 'info').
> Solution:
>  * Add proper category when we invoke *flash()*.
>  * We can't use category 'error'. In bootstrap-theme.css, we don't have `alert-error`
(we have `alert-danger` instead).
> *Latest update:*
> we update bootstrap-theme.css, to add CSS classes 'alert-message' and 'alert-error'.
This may help minimize the changes we need to do.
