When I try to open an eiffel sourcefile with
eclipse-3.2 and edt I get the following error:

Problems occurred when invoking code from plug-in:
"org.eclipse.jface".

I've exactly the same error on the same Eclipse version, but
on the normal x86 architecture. I'd really like to use the
editor; so, is there any news about this severe trouble?

[costamojan]

We will check for this after the next release.

org/eclipse/ui/internal/texteditor/AnnotationExpansionControl has been moved to org.eclipse.dltk.mod.internal.ui.text.hover.AnnotationExpansionControl since 3.2. This is what is causing the error.
