Thanks Murthy,
Deleting those tags solved those issues specific to jforum for our
campus.
We were still getting period reports of users having that issue with
mailtool as well. As it turns out "defer =1" appears in a whole bunch
of sakai code (we're running 2.5.3.x)
e.g.
cd /usr/local/sakai/webapps/library
find . -exec grep "defer" '{}' \; -print
// <script type="text/javascript" defer="1">chef_setupformattedtextarea
("MyTextareaID", 640, 480);</script>
./editor/CrossBrowserRichtextEditor/sakai_editor_twinpeaks.js
// <script type="text/javascript" defer="1">chef_setupformattedtextarea
("MyTextareaID", 640, 480);</script>
./editor/CrossBrowserRichtextEditor/sakai_editor.js
// <script type="text/javascript" defer="1">chef_setupformattedtextarea
("MyTextareaID", 640, 480);</script>
./editor/FCKeditor/sakai_editor_twinpeaks.js
// <script type="text/javascript" defer="1">chef_setupformattedtextarea
("MyTextareaID", 640, 480);</script>
./editor/FCKeditor/sakai_editor.js
<SCRIPT defer>
./editor/HTMLArea/popups/old_insert_image.html
><span class="function-name"><</span><span class="html-
tag">script</span> <span class="variable-name">type=</span><span
class="string">"text/javascript"</span> <span
class="variable-name">defer=</span><span class="string">"1"</
span><span class="function-name">></span>
./editor/HTMLArea/reference.html
// <script type="text/javascript" defer="1">chef_setupformattedtextarea
("MyTextareaID", 640, 480);</script>
./editor/HTMLArea/sakai_editor_twinpeaks.js
// <script type="text/javascript" defer="1">chef_setupformattedtextarea
("MyTextareaID", 640, 480);</script>
....
So we're evaluating what to do at this point (how much to edit). The
error doesn't always happen but it seems more likely on a slower
network connection.
