I don't think that Eclipse is to blame for all of them (UTF-8 in the path excepted). I think you are just blaming Eclipse for problems whose source lies elsewhere. > For instance, one application with ERAttachments that was working, after I > experimented some changes in the database with migrations, Did you change the model? > started to throw exceptions regarding the primary keys.

Sometimes a working > project will cease to work for no apparent reason, Because the reason is not apparent to you, does not mean that the reason is Eclipse. Most of us here use it on a daily basis and we don't have these problems.

That means that the JavaEOProject framework needs to be added to the project you are generating SQL from. I think this may only be added to Application projects by default. Or perhaps you removed it? > I have my models and connections in a framework that is currently being used > by three applications.

But differences in the frameworks included in each project could be the reason. Frameworks used by a Framework project are NOT available to an Application project. They need to be added to the Application project as well. > I even used Practical Web Objects' EOFJDBCConnectionAnalyzer to debug the > connection with no luck in finding the problem.
