In IntelliJ 2024.3 EAP 7, the JCEF browser preview gets stuck initializing the preview

[jtiee]

Observed vs. expected behavior

Observed: Opening an AsciiDoc file in a tab opens the preview pane, but it says Initializing... indefinitely.

Expected: Opening an AsciiDoc file in a tab opens the preview pane, and the AsciiDoc preview renders.

Steps to reproduce

1. Update to IntelliJ 2024.3 EAP 7.
2. Make sure the AsciiDoc plugin is installed and enabled.
3. Open an AsciiDoc file.

Environment

Plugin Version: 0.43.1

Thank you for reporting this. I'll have a look.

I'm trying to reproduce it on Linux. I see this happening when I first open an AsciiDoc editor. Once I close it and open it again, the preview is there.
How does it look for you?

[ahus1]

There is now pre-release 0.43.2 of the plugin which includes a change which should fix the issue you described, although I am not 100% sure if that what I observed was the same problem you observed.

Please give this preview release a try an let me know if it works for you.

The pre-release of the plugin is available from GitHub releases and the IntelliJ AsciiDoc EAP repository.

I've tried 0.43.2, and it works well. Thanks for fixing the issue so quickly!

Before I filed this issue, I did once see that closing and re-opening an editor would start the preview correctly. After that one instance, the plugin got stuck in Initializing... every time.

Thank you for testing it, and I'm glad it works. I'm closing this issue now, and I am promoting the preview to a real release.
