Hi everyone, recently I got a problem as you can see from the title. Hope you can give me some tips (solutions better). Thanks a lot.
 
 
 Platform
 OS: Ubuntu 12.04
 Eclipse: Java Developers Edition, Indigo SR2
 Hibernate-tools: 3.4.x for Indigo (I download it from Marketplace)
 
 
 Situation
 After installed the Hibernate-Tools, whenever I use content assist, Eclipse shows the dialog below:
  http://www.eclipse.org/forums/index.php/fa/10833/0/  (http://www.eclipse.org/forums/index.php/fa/10833/0/)
 
 Moreover, when I do something relation to dialog, Eclipse also shows the dialog like this:
