怎样删除一个Aptana里面错误的连接

There is no "Connection Manager" that you can delete it (I can't find it). I found one way to delete old or faulty FTP connection (let's say it's 'connection123').

Create new Web Project (or choose existing)Click right on 'Connections' and select 'Connection Manager'Click green '+' and change name for example 'Name1'; in 'Source' choose 'Project'; in 'Destination' choose 'Remote' and select connection (our 'connection123') that you want to modify or delete; Apply or OKUnder 'Connection' in Project Explorer View our Connection appear ('connection123')Click right on 'connection123' and choose 'Delete'

IT'S DONE! ;-)
