Window Builder crashes when doing anything on the Design tab

[tobieche110]

Hi! So, I recently installed this plugin. I can't manage to get it to work. I can access the Design tab when I create an Application Window class, but if I try to do anything (inserting a button in the window, redimensioning it, anything) I get this error:

(This particularly happens when I try to redimension it)

I've googled the issue a lot and I can't find any solution. At fist I thought it was an error from this specific project, but it happens even on fresh new projects without any other class.

When I try to run the program, the default window opens, and it seems to work, but I still get this problem.

Please help me.

[mrmark1998]

Same here! I have been trying to fix it by Googling various errors for about 2 hours now. I am at my wits end. I've tried the following already which did not work and almost broke my Eclipse and previous codes completely:

• Installed latest Eclipse version (2022-09) - caused a wreck on my Workspace folder, and didn't even recognize WindowsBuilder at all
• Made to sure Install WindowsBuilder AND WindowsBuilder Nightly Build App (latest versions)
• Searched for newest JDK versions, which came out to be JDK19 it seems. Also tried installing jvm1.8xx which didn't work either...

Tinkered with the above for 2 hours. The new eclipse sucked because not only did it not have Dark Mode, but all the icons were super small and like I said, it didn't even allow me to create a WindowsBuilder Application Window under New->Other-Swing Designer ??? Maybe you can try what I did and it will work for you but I am still stuck.

Any help for us newbs would be great!
