Window Builder crashes when doing anything on the Design tab

[tobieche110]

Discussed in #345

^{Originally posted by tobieche110 October 25, 2022}
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.

[Unluckyjoker]

Same problem here

[RyukTV]

Same problem here I try everything but it the same problem

[kareemz32]

Anyone figure out how to fix it yet?

[merks]

The missing method was added during the 2022-09 release cycle so you'll need to update JDT to the latest release, e.g., from this site:

https://download.eclipse.org/releases/2022-09/

@tobieche110 Good evening.
I'm having the same problem and I can't figure out how to solve it. I saw that you are from Argentina. I'm from Spain, if you could help me I would be so grateful. We can comunicate via Discord if you want. Thank you.

[alfonso-lopezr1-um-es]

Hey. I think the last update on WindowBuilder is causing all this mess. You can download a previous version and it will work. You can contact me via twitter if you want: @alforjaalegria

[michaelskyba]

Did you try updating Eclipse, like merks suggested?

[Rithvikchowdary]

This issue can be solved by doing some steps

1. Go to Help option on eclipse ide
2. And click on market place
   3)Search Windows builder
   4)And update Everything which doesnot shows installed option
   5)And restart the Eclipse
