I've been playing with Dallas one wire sensors etc for sometime as they are reasonably cheap. The end plan is to control the house heating system intelligently. Currently we have a standard two zone system with a boiler.

Hi! I've added a new user, after that I've added some data sources. When I try to give that user access to the new data sources (in the "Users" page) I've got an error message: PreparedStatementCallback; SQL [update users set username=?, password=?, email=?, phone=?, admin=?, disabled=?, homeUrl=?, receiveAlarmEmails=?, receiveOwnAuditEvents=? where id=?]; An attempt was made to get a data value of type 'VARCHAR' from a data value of type 'null'.; nested exception is java.sql.SQLDataException: An attempt was made to get a data value of type 'VARCHAR' from a data value of type 'null'. The same message I've seen trying to change user password.

Ah. There isn't a way to get that via an AJAX update, but there should be a way to it if you draw it in JSP. I've never had to do it, so i'm not sure.

Oops... I've missed that button :oops: Thanks a lot!

Yes, it is.

Thanks. A fix for this will be in the next release.
