英文:
Why is the Design tab in the WindowBuilder editor empty in Eclipse 2020-09?
问题
升级到Eclipse 2020-09（4.17）后，在WindowBuilder编辑器中，Java代码显示在“Source”选项卡中（如预期），但是“Design”选项卡中再也没有显示任何内容。我预期图形编辑器会显示在“Design”选项卡中，就像我升级之前的情况一样。
英文:
After upgrading to Eclipse 2020-09 (4.17) in the WindowBuilder editor the Java code is shown in the Source tab (as expected), but nothing is shown in the Design tab anymore. I would expect that the graphical editor would be displayed in the Design tab, as it was the case before I did the upgrade.
