There have been similar reports in the past. Would you try the latest version (2.3) to see if you still have the error? Also, this known bug may be related:
http://issues.apache.org/jira/browse/IBATIS-357 It might seem unrelated on the surface, but I belive the error maybe in the same area of the code. Anyway, let us know if it's still broken with the latest version. If we can get a reproducible test case, then we can take a look at it. Jeff Butler On 6/28/07, lee_will <[EMAIL PROTECTED]> wrote:
I came across the issue when I used TypeHandler in <resultMap> and I believe it's a bug. Here is the case: There're two columns, "date_read" and "date_created" in the "messages" table (MySql database), they are type of "Datetime" and "Timestamp" respectively. I was trying to convert them to string using type handler (SimsDateToCharTypeHandler). <typeAlias alias="myDateToChar" type="myPackage.util.SimsDateToCharTypeHandler" /> <resultMap id="messageInfoResult" class="myPackage.MassageInfo"> <result property="dateRead" column="date_read" typeHandler="myDateToChar "/> <result property="dateCreated" column="date_created" typeHandler="myDateToChar "/> <!-- more mapping --> </resultMap> <select id="getMessagesByUserName" resultMap="messageInfoResult" > SELECT date_read, date_created FROM messages </select> "date_read" can be "null" value but "date_created" is always populated with "current time" in database. When the order of elements in <resultMap> is as above and if "date_read" is NULL, "dateCreated" property in "MassageInfo" object will be NULL. This is not right since "date_created" HAS value so that "dateCreated" property should be something like "07/01/2006 11:30", rather than "NULL". However if I reverse the order of elements in <resultMap>, i.e., <resultMap id="messageInfoResult" class="myPackage.MassageInfo"> <!-- order of these two is reversed --> <result property="dateCreated" column="date_created" typeHandler="myDateToChar "/> <result property="dateRead" column="date_read" typeHandler="myDateToChar "/> <!-- more mapping --> </resultMap> Then I'll get correct result, e.g., dateCreated could be "07/01/2006" but "dateRead" is null. The iBatis version is 2, I'm not sure if you've fixed it in the latest version. -- View this message in context: http://www.nabble.com/iBatis-bug-report-tf3995995.html#a11348464 Sent from the iBATIS - Dev mailing list archive at Nabble.com.
