SID-00766: TinyMCE editor adds 'phantom' whitespace

Status:	Unanswered	TWiki version:	4.1.2	Perl version:	5.8.8-12ubuntu0.4
Category:	TinyMCEPlugin	Server OS:	Ubuntu 8.04	Last update:	15 years ago

When using TinyMCE editor on 4.1.2, 'phantom' whitespace is added to the end of each line using Firefox 3.5.8 or IE7.0. Clicking to the right of a line of text positions the cursor as if there was a space at the end, arrow keys can move over the 'space'.

Under Firefox, attempts to delete it remove the last 'real' character in the line, and the 'space' still appears on clicking to the right of the line or pressing the 'End' key on the keyboard.

Under IE7.0, the space is deleted, but reappears when the topic is saved and re-edited

I tried to reproduce it on http://twiki.org/cgi-bin/view/Sandbox/RandomTestTopic8349 but it only seems to happen on some lines, with no obvious pattern (line length, punctuation etc)

Copying and pasting the text via notepad seemed to make the phantom spaces go away

This does seem to replicate it consistently on the public sandbox:

• go to http://twiki.org/cgi-bin/view/Sandbox/WebHome
• log in as TWikiGuest with password guest (as instructed on the page)
• Click on the red link at http://twiki.org/cgi-bin/view/Sandbox/WebHome#Create_your_own_Sandbox_Page
• on the resulting editor, click off to the right of the date beside the bottom line
• use arrow keys to move back and forth around the final 'space'
• use backspace to delete the final 'space' and note that the last digit of the date disappears instead.
• Press End key on your keyboard and confirm space reappears
• Repeat until convinced...

Fails on Firefox 3.5.8 as described

Works partially on IE7.0 (both the Sandbox test above and access to our 4.1.2 server), allowing space to be deleted, but then re-creates it when topic is reopened

Reopened as still needed. Info above should be sufficient to reproduce, so hope someone else can confirm or suggest better workaround?
