    Hi Len,

    Are you using MySQL database?
    It seems that there is an issue when saving xml values to the MySQL database. The controls which have such properties are ContentView, NewsView, BlogPosts.

    The problem is that MySQL adds a '?' symbol in the beginning of the xml string. We are still investigating a reason for that and are on the way to fix it. The fix will be included in next release. 

    For the time being we can suggest that you apply the workaround described below:
    Modify the two stored procedures in the database: sf_CmsControlProperty_upd and sf_CmsControlProperty_ins.


    In sf_CmsControlProperty_upd replace `Value` = P_Value  with `Value` = Replace(P_Value, '?<?xml', '<?xml')
    CREATE DEFINER=`root`@`localhost` PROCEDURE `sf_CmsControlProperty_upd`(in PO_ControlID varchar(39), in PO_Name varchar(54), in P_ParentID varchar(39), in P_ParentName varchar(54), in P_Value longtext) 
    BEGIN 
        DECLARE _msg TINYINT; 
        UPDATE `sf32`.`sf_CmsControlProperty` SET `ParentID` = P_ParentID, `ParentName` = P_ParentName, `Value` = Replace(P_Value, '?<?xml''<?xml'WHERE `ControlID` = PO_ControlID AND `Name` = PO_Name; 
     
        IF (row_count() <> 1) THEN SET _msg='error'END IF; 
    END 


    In sf_CmsControlProperty_ins replace P_Value with Replace(P_Value, '?<?xml', '<?xml')
    CREATE DEFINER=`root`@`localhost` PROCEDURE `sf_CmsControlProperty_ins`(in P_ControlID varchar(39), in P_Name varchar(54), in P_ParentID varchar(39), in P_ParentName varchar(54), in P_Value longtext) 
    BEGIN 
        DECLARE _msg TINYINT; 
        INSERT INTO `sf32`.`sf_CmsControlProperty` (`ControlID`, `Name`, `ParentID`, `ParentName`, `Value`) VALUES (P_ControlID, P_Name, P_ParentID, P_ParentName, Replace(P_Value, '?<?xml''<?xml')
         
    END 

    These changes can be made using the MySQL Administrator tool.

    I hope this workaround will be of help.
    Let me know if you more assistance is needed.


    Sincerely yours,
