[opencms-dev] "Edit page" gives 500

[hagen.altmann at o2online.de]

Hi, I've got the same problem as Kim:
http://mail.opencms.org/pipermail/opencms-dev/2004q1/010031.html

Unfortunately, his workaround doesn't work for me. Before I tried out his 
hints I got the same error (404). Now I keep getting a 500..

The log tells me the following:
[30.07.2004 22:21:44] <opencms_info> [CmsElementXml (CmsXmlTemplateEditor/edit_page_main)] Error 
in getContent for template class com.opencms.workplace.CmsXmlTemplateEditor

The stack trace tells this (long) story:
