Thanks for your reply Jeff
I am using something very similar (See below) but I am getting a host of
error messages, including:
--- Cause: com.ibatis.common.beans.ProbeException: Error getting ordinal
list from JavaBean. Cause java.lang.NumberFormatException: For input string:
""
Caused by: java.lang.NumberFormatException: For input string: ""; nested
exception is com.ibatis.common.jdbc.exception.NestedSQLException:
followed by:
com.ibatis.common.beans.ProbeException: Error getting ordinal list from
JavaBean. Cause java.lang.NumberFormatException: For input string: ""
These are repeated several times.
I pass a HashMap into the SQLMap. One of the instances is a ReportParameters
instance. This is comprised of several properties but the important one as
far as my SQL is concerned is an array of objects which themselves contain
an array.
My SQLMap dynanically builds a WHERE clause based on the ReportParameters
'outer' and 'inner' arrays. The <dynamic> block looks similar to this:
<iterate prepend="AND" property="ReportParameters.outerArray"
conjunction="OR" open="(" close=")">
(
#ReportParameters.outerArray[].someProperty#
...
)
<iterate prepend="AND"
property="ReportParameters.outerArray[].innerArray"
conjunction="AND" open="(" close=")">
(
#ReportParameters.outerArray[].innerArray[].anotherProperty#
)
</iterate>
)
</iterate>
I'm not sure why this is happening at all. The syntax looks straight-forward
and intuitive and yet it (or something) appears to crash iBatis.
I have dumped the contents of ReportParameters just before I execute the SQL
via my DAO. Everything looks as expected.
The version of iBatis I am using is v2. The app uses ibatis-common-2.jar and
ibatis-sqlmap-2.jar
