[xwiki-users] Problems with Livetable Macro on MsSql database

Hi users, I installed xwiki-3.3.1 using MsSql. I works quite well. I found only one problem. The lifetable marco in the document index page does not work. In the log file I found the following logs: 2012-02-14 08:50:41,161 ERROR [http://cloud12-288:8080/xwiki/bin/get/XWiki/LiveTableResults?outputSyntax=p…] o.h.u.JDBCExceptionReporter [JDBCExceptionReporter.java:234] Fehler beim Konvertieren des varchar-Datentyps in float. The jdbc error message is in German, because it is the german jdbc driver. Translated into english it means Error: Cannot convert varchar datatype into float Can someone help me. Is it an error on the jdbc level or is it a problem of the life table marco? Richard
