After editing a topic that contains pre-Tags with wysiwyg all linebreaks are deleted.

e.g. create a topic with raw-edit


edit and save with wysiwyg:

<pre>test test test</pre>

Okay guys, any ideas? Any flash of inspiration what causes this bug?

I believe I solved the problem in my 1.0.6 installation with the patch below. I would be grateful for a confirmation or a correction to my approach.

@FulvioScapin: I tried your patch and it does honor linefeeds and spaces, but HTML entities are shown as &entity;:
 &lt;-- at the beginning
two spaces here --&gt;[  ]
looks like this in TinyMCE:

 &lt;-- at the beginning
two spaces here --&gt;[  ]
Note the additional linefeed at the beginning. Is this OK?
Plus, the PRE box is rendered 2 lines tall in Firefox 3.5, but that happened before your patch.

This works on trunk, except that TMCE itself eats the newline after the <pre> tag, so
However, the presentation is the same before and after removal of the newline so I do not think that is a problem.

I have added unit tests to ensure that this stays fixed. Changing state to "waiting for release". (If you disagree, please change it back smile )
