Script-Error with Firefox in ADE sitemap editor

[kartobi]

Firefox pops up an alert window "Warning: Script not responding ..." when opening the sitemap editor.

Seems only to happen when the level of my current page is four or more.

I can not reproduce this issue, please state which Firefox version and OpenCms version you are using.

This problem only occurs with large sitemaps.

[tHerrmann]

Please check out OpenCms version 8.5. We did some performance enhancements on the sitemap editor for that version.

Uh, can't remember the firefox version two months ago. But still occurs with current version 16.0.2
OpenCms version is 8.0.4

I'll give 8.5 a try...

I have the same problem. It is due to loading these resources:

resources/filetypes/containerpage_big.png
resources/filetypes/image_big.png
resources/filetypes/pdf_big.png

Their loading takes about 9.5 second (loading starts at the same time, it waits about 9.5 seconds and all finish at the same time).
When I write url to some of those resources directly to browser address bar, the resource is returned immediately without waiting.

OpenCms 8.0.4, Firefox 12 (CentOS) and 17.0.1 (Windows 7).

In Chrome 23 (Windows) it works properly.

Please check if this issue remains in version 8.5.1 other wise I will close this issue.

I assume this issue is resolved with release version 8.5.1.
