Servoy Forum

I'm using the Community Edition Version: 8.4.0.3402 on Windows 10.

Any attempt to use the context menu Refactor/Extract Method... on any JavaScript code produces the following error:

---
An unexpected exception occurred during condition checking. See the error log for more details.

org/eclipse/ltk/internal/core/refactoring/Resources
---

The error log, shown below, implies that there is a missing class, if I read it right.

Is this supposed to work?

Is there a fix for it?

thanks,

Terry

There is indeed a problem with extracting methods in 8.4.

I just tried it in 2019.03 and there it works as expected again.
