Links in internal Russian Help works very strange

[calibrator]

Now first call to Russian Help (in Russian version) JOSM 2916 works correct. But if click on any link, then next page of internal Russian Help looks very strange. See attached PrintScreen file, please.
PS: English Internal Help works correct.

PPS: I can not attach file to ticket. I recieve error message during upload to Track:

Trac detected an internal error:

Copy file first to C:\ and upload then. Seems this is a Trac bug - Trac should ignore that error as it is anyway in stripped part of the path.

[calibrator]

Done.

[stoecker]

Same for all languages.

It seems to be a bug in JEditorPane.setPage() method which is called in HelpBrowser.openUrl() for all pages that doesn't start with "​http://josm.openstreetmap.de/wiki/Help".

[stoecker]

Probably we need to load the page directly like the JOSM help pages. We should reset the CSS for pages not from ​http://josm.openstreetmap.de/.

Problem shows in those wiki pages that doesn't start with "Help", for example ​http://josm.openstreetmap.de/wiki/Introduction

Probem in CSS sheet indeed: ​http://josm.openstreetmap.de/chrome/common/css/trac.css

body { background: #fff; color: #000; margin: 10px; padding: 0; }

I think #fff is interpreted as #000fff by Java.

Possible solutions:

• use fetchHelpTopicContent() for all JOSM wiki pages, not only these that starts with "Help"
• Find a way to make JEditorPane.setPage() ignore CSS stylesteets.
• Do not use JEditorPane.setPage() at all, use HttpURLConnection + JEditorPane.setText(), but do not prettify contents with prepareHelpContent().

I tested without CSS and I got a page which looked binary (German help, click on link to OSM webpage). Probably setPage() did not undo gzip for the contents.

Best seems to switch to own loader for all pages and handle correctly handle the CSS settings.
