Windowsbuilder design error przy SWT [message #819217]

Cześć, zainstalowałem sobie windowbuildera do eclipsa 3.7, potem ściągnąłem biblioteke zgodnie ze wskazówkami z eclipse org/swt/eclipse php

I ok wczytało klasy bo kod już nie był czerwony, program mogę odpalić, lecz gdy chcę wejść w Design to dostaje błąd

WindowBuilder encountered unexpected internal error. 

This could be caused by a WindowBuilder bug or by a misconfiguration issue, conflict, partial update, etc.

java.lang.ClassCastException: org.eclipse.swt.widgets.Shell cannot be cast to org.eclipse.swt.widgets.Control

Na samym dole posta dam wyciąg z stack trace'a
Próbowałem też paru innych sposobów żeby wgrać to swt

- Ściągnąłem nowego eclipsa
- Dołączałem ręcznie swt.jar
- Próbowałem korzystać z workspace bez spacji w nazwie(gdzieś taki przypadek wyszukałem)
- Próbowałem różnych wersji SWT

Ogólnie już ze 2 godziny szukam rozwiązania po forach i bezskutecznie, więc będę wdzięczny za jakąkolwiek pomoc.

This could be caused by a WindowBuilder bug (...)

Skoro tak to zgłoś im buga. Nie zapomnij napisać jakiej wersji WB używasz, z jakim Eclipse. Przydadzą się też kroki instalacji/konfiguracji (może tam coś przeoczyłeś) i kroki które kończą się wspomnianym stacktracem.

Doradzałbym odinstalowanie WindowBuildera, a po restarcie środowiska Eclipse ponowne jego zainstalowanie - być może coś nie do końca dobrze się pobrało i/lub zainstalowało. W jaki sposób instalujesz? Jakie repozytorium? Jakie wersje Eclipse, WindowBuildera, Javy? Wybierasz jakieś opcje przy instalacji? Wymaganymi składnikami do poprawnego działania WindowBuildera są JDT i PDE (PDT akurat konkretnie dla SWT, nie ma ich w paczce Eclipse Classic, więc trzeba doinstalować).

Nowy projekt SWT można stworzyć w następujący sposób: File->New->Other->WindowBuilder->SWT Designer->SWT/JFace Java Project. W ten sposób do projektu zostaną dołączone wszystkie wymagane biblioteki, w tym i SWT (bo tak naprawdę bibliotekę SWT otrzymujemy z Eclipse (zerknij do podkatalogu plugins i poszukaj pliku jar zaczynającego sie od od org.eclipse.swt...).
