Recording:

I want to override the preVisitDirectory method, but when I press Tab (or Enter), an exception occurs and my input is wiped:

Hi @anthonyvdotbe. Thank you for raising this issue.

It may be fixed by #520, which will be delivered in the 25.0.1 release. The error stacktrace you have shared appears to be similar. That issue was typically triggered when the imports required by the overridden method are being added to the file by the completion. In order to check if your issue would be fixed by that, you may try adding the required imports to your file first and then attempting the suggestion. Example in this case: imports for java.nio.file.*, java.nio.file.attribute.*, java.io.IOException.
Note that this is not a workaround, but just a quick check if this issue in your environment would be fixed by the referenced PR.
The workaround in the interim is to trigger code suggestions (e.g. with ctrl+space) without typing any prefix for the overriding method name and then selecting the required method.

Do let us know whether this works. Thanks.

This doesn't work, the issue still occurs.

This works, thanks.

Hi @anthonyvdotbe. The fix discussed above was delivered in version 25.0.1. You may try this out now.
Please let us know if this still does not work for you. Thanks.
