Could you verify the issue I found is really a bug in version 1.2.0? Below my steps:
1. In file
index.htm in line 17 I changed the date values from:
source: [{"name":"application","desc":"Lübeck","values":[{"from":"/Date(1293874598708)/","to":"/Date(1354268198708)/","desc":"ID: 10<br/>name: CRM<br/>date: 01.01.2011 to 30.11.2012<br/>description: CRM 4.0", "label":"CRM","customClass":"ganttGreen"}]}],
to:
source: [{"name":"application","desc":"Lübeck","values":[{"from":"/Date(1332313200000)/","to":"/Date(1332828000000)/","desc":"ID: 10<br/>name: CRM<br/>date: 01.01.2011 to 30.11.2012<br/>description: CRM 4.0", "label":"CRM","customClass":"ganttGreen"}]}],
1332313200000 - it is: Wed Mar 21 08:00:00 CET 2012
1332828000000 - it is: Tue Mar 27 08:00:00 CEST 2012
2. On chart I can see the box but in other invalid date range: from Mar 21 to Mar 26.
What may be a problem? A time zone maybe? I have many different values on my chart and I notice only some are invalid, not all, probably it depends on specified data.
