Eclipse 3.2.2 content assist not finding classes in the project

In Eclipse 3.2.2 on Linux content assist is not finding classes within the same project. Upgrading above 3.2 is not an option as SWT is not available above 3.2 for Solaris.

I have seen suggestions to clean the workspace, reopen the workspace, run eclipse with the -clean command, none of which has worked.

From stackoverflow Ryan P

• Go to Java/Editor/Content Assist/Advanced in Preferences, and make sure that the correct proposal kinds are selected. Same kind of thing happened to me when I first moved to 3.4.

  Ryan P : I have tried multiple things in the content assist preferences including: * Turning off all content assist, cleaning, then re-enabling * Turning on all content assist, then cleaning * Restoring defaults on content assist, then cleaning * Most of the in between

• Are you sure that "build automatically" in the Project menu is checked? :-)

  Another thing: is the Problems view, unfiltered, completely clear of compilation errors and of classpath errors?

  Ryan P : Yes on both counts
  From Damien B

• Thanks for your last comment it worked partially. If there is any kind of errors, the content assist wont work. Once fixed, it partially works. I say partially because, there appear to be a bug, when I do Perl EPIC inheritance ex:

  package FG::CatalogueFichier;
  use FG::Catalogue;
  our @ISA = qw(FG::Catalogue);
  use strict;
  

  , the inheritted subroutines are not displayed in the content assist.
