When doing right click new-> entity classes from database, and I use a datasource (mysql url) to get tables from, 
the ide never shows Grey color for tables for which entities already exist. In version 5.5 this was done.
I was using the add all feature and then it would add to the right row only the tables for which entities did not exist.
In fact sometimes it this was done on the second try (after pressing cancel). But it was done. 
In 6.0, I delete only one entity, but I see no grey tables on the left list of the dialog. 

Thanks
