jsMath problems

Hi All,

I'm just working on a colleague's Moodle site and discovered this issue: they have jsMath installed but when I go to a "Define roles" page then I see a span tag inserted by jsMath (please see attached screen shot).

Just looking through the forums I see others have had similar problems. Is there any solution?

Site details: Moodle 1.9.4 (about to be upgraded) on shared hosting.

Another issue I'm having is that Moodle seems to freeze IE on the "Define roles" pages. If I turn off the jsMath filter then the problem is solved smile. Except I need jsMath installed on this Moodle sad.

Thanks in advance,

Ian.

Well I remember one similar case 2 years ago http://moodle.org/mod/forum/discuss.php?d=78614

<span id="Process_jsMath"></span> seemed to cause

jsMath.Autoload.Script has no properties error...

For example jsMath itself could probably have some check that removes empty tags <span id="Process_jsMath"></span> but I have never tested how jsMath creates those tags - because I haven't used jsMath, just quickly tested it a couple of times.

Thanks Mauno. Am I right in thinking that this is basically a bug in the jsMath filter?

It is clearly a bug in jsMath filter - jsMath should check that either it has some maths inside those tags or it should clean "empty notations"

Filter just renders tags (or hides them) but editor or some plugin might be used to totally clean them from inner html before saving...

Double check jsMath version. I think there were some major changes made a year os so back. I think jsmath is at 3.6??

I don't think filter has been changed since 1.9.2, but Davide maintains filter as well as app


Looks like Davide is on sabbatical. I emailed his university address to see if he was available to look at this in the mean time.
