Item5294: Wysywig & TinyMCE corrupt some topics.

• < and > markup is changed to span tags. Causes the enclosed dot tag to be interpreted.
• verbatim tag inside a sticky block is changed to verbatim missing the leading less-than and followed by hex characters EF.BF.BD
• explicit html break tags are removed from inside sticky blocks
• text within a pre block is all run together
• nbsp is removed

To recreate, edit the DirectedGraphPlugin topic and save it without making any changes. Attached is a "diff" of the changes made after a simple edit/save. Note that the DirectedGraphPlugin does not need to be installed to observe the issues.

(Running from SVN rev 16300)

The <dot> ( dot-in-angle-brackets ) issue is generic to 4.2.0 WYSIWYG edits of <enter> ( enter-in-angle-brackets ) -- they don't survive round trips through a WYSIWYG edit.

Also &2013; becomes %2013 for some reason in 4.2.0.

We are running off the-shelve Twiki 4.2.0 + late January TinyMCE (TWiki-4, $Rev: 16290 (25 Jan 2008) $) and Wysiwyg plugins (TWiki-4.2, $Rev: 16350 (06 Feb 2008) $) as suggested in Known Issues and additionally TWikiDraw plugin Dakar, 8154

I suppose this is variation of this bug, but a rather bad one. Editing TWikiPreferences causes some problems. For example, it insert a couple of spaces after setting for ICONTOPIC resulting in all the skin icons being broken. Don't know yet what other mischief it causes.

Can you please provide step-by-step instructions on how to reproduce this problem. 90% of the time spent on fixing bugs is in trying to build a testcase that reproduces the problem, so step-by-step would be very helpful, thanks.

No worries, I have seen the angle-brace problem myself. Confirmed.

Mostly this is due to two issues; first, that verbatim and literal tags have higher priority than sticky, which is clearly a mistake. And second, that angle brackets are being mishandled, due to the fix for Item5179. The problem with newlines in pre blocks is specifically tracked in Item5337 and appears to be a bug in Tiny MCE, or perhaps in the browser.

Fixed all (I think) except the space-in-pre issue, which is tracked in Item5337. Merged to TWikiRelease04x02.
