Even though “middle” seems to be interchangable with “center”, we will investigate the behavior you mentioned. Thanks for the information.
The validation check you mentioned is actually a new behavior in beta2. In previous versions of MyEclipse, the HTML tidy integration has a incremental builder that would validate and mark html files with annotations of warnings and errors automatically. In some of the use cases reported by our users, this was causing a problem because they were importing thousands of html files and didn’t want to wait for html validation to process all of them. So in beta2, we disabled the incremental builder by default. You can re-enable this feature in the preferences under
MyEclipse->Editors->Jsp/HTML Editor->HTML Formatting & validation
At the top of this page you will see an option for “Enable Incremental HTML validation”. If you check that, then all html files will be validated on save.
