Question

I'm trying to build a table with a gauge on each cell. If I insert more than 3 gauges it stops working (the page doesn't loads in the browser, and after a while, it timeouts). The problematic code is this:

*

C4

C7

C8

C9

C10

C11

C12

C13

As you can see, it works in the Twiki.org server, but on mine it doesn't. What further information can I provide to help pinpoint the problem on my server? When the browser is trying to display the page, a "/usr/bin/perl -wT /var/www/twiki/bin/view" process is launched, and it keeps running consuming almost no CPU. It stays running until the browser (or the server) timeouts.

Further info:

in the apache error_log, the following lines appear whenever you try to view the problematic page:

[Tue Jul 13 13:58:04 2004] [error] [client YYY.YY.YY.YY] [Tue Jul 13 13:48:05 2004] view: Use of uninitialized value in pattern match (m//) at ../lib/TWiki/Plugins/GaugePlugin.pm line 111., referer: http://XXX.XX.XX.XX/twiki/bin/view/Test/EstadisticasTest [Tue Jul 13 13:58:04 2004] [error] [client YYY.YY.YY.YY] [Tue Jul 13 13:48:05 2004] view: Use of uninitialized value in hex at ../lib/TWiki/Plu gins/GaugePlugin.pm line 113., referer: http://XXX.XX.XX.XX/twiki/bin/view/Test/EstadisticasTest [Tue Jul 13 13:58:04 2004] [error] [client YYY.YY.YY.YY] [Tue Jul 13 13:48:05 2004] view: Use of uninitialized value in hex at ../lib/TWiki/Plu gins/GaugePlugin.pm line 114., referer: http://XXX.XX.XX.XX/twiki/bin/view/Test/EstadisticasTest

OK! Found the problem: I was defining an extra area for the gauge (4 in total). The default Gauge has 3 areas. The code only has default colors defined for 3 areas. If I define the colors for the 4 areas, it works ok on my server. Maybe the default installation of the GaugePlugin in the twiki.org servers has more colors defined by default.... who knows.
