Error while parsing

It's not a module bug.

The author of the visualization applet has confirmed to me that this error happens with some versions of the Java runtime users have installed on their machines. The author is looking into possibilities of a patch within HyperGraph that would bypass the Java bug. He knows it is urgent but we can't estimate when he finds the time to look into it. Let's hope it will be very soon.

If any of the readers knows Java so well s/he can fix it, please don't hesitate - the open source code is at http://hypergraph.sourceforge.net/

Cheers,

Vacilando (I am just the module author)

I've found out that if you turn Java caching off (go to Java control panel, find settings for "Temporary Internet Files", turn them off), the problem disappears. A generic solution would be to switch off caching using an applet parameter -- if anybody knows how to do that, please contact the author.

Subscribing.

After many sleepless nights I found it was a bug related to Drupal ( see my full analysis here )... nobody has been able to explain why it happened, but I was nevertheless able to make a workaround. So v1.3 fixes this issue (and adds a number of other improvements).

There was a bug when HG was used together with Devel (and maybe other modules).

See http://drupal.org/node/237239 for more, get v1.4 for the patched version from http://drupal.org/project/hypergraph

Let me know if this did not fix the issue for you.

I have the same parsing problem with 1.4 version

I've tried to turn off the "Temporary Internet Files" in the Java control panel but the bug persist

Same problem here. This module breaks and using it will frustrate your visitors.

This error does not stem from the Drupal module, but from the Java applet itself.

I urge everybody who would like to see this fixed to go to http://hypergraph.sourceforge.net/ and
1) either contact the author of the applet kindly asking for a fix or explanation of this error
2) or try to find and fix the problem yourself in Java
(It could be as simple as escaping something illegal in the data input -- but what?)

Me, I did try to contact the applet's author (1) but never tried (2) as my Java skills are not good enough.

I have been looking at the module myself, and if it is a java error, why does the module work on http://vacilando.net/hg on all pc's I have tried, but not on my system at drupal.mos-eisley.dk - The java beneath should be the same...? I even tried to copy the jarfile from http://vacilando.net/ - same issue ?

If I do try the "XML" link for the applet parameters: http://drupal.mos-eisley.dk/site/modules/hypergraph/graphs/hg.php?par=0&..., I am just send to the drupal installation of my site, no XML output arrives...

BR,

I have the same problem... I have a pretty vanilla Drupal 6.14 install and no Devel. I have tried changing the java version locally and disabling the Java cache all to no effect.

I love Hypergaph and hope this weird bug is squashed soon.
