Subject Problem accessing List instance property via <isnull>
Date Mon, 26 Apr 2010 19:02:41 GMT

Hi

I'm new to iBatis and I'm struggling to access a property of instances
stor4ed in a list which, in turn are passed to ibatis in a HashMap
parameter. The <iterate> clauses are building a WHERE clause, the contents
of which will alter depending on whether this proeprty is null or not.

I am iterating over my List as follows:

<iterate prepend="AND" property="MyMap.myList" conjunction="AND" open="("
close=")">
    ...
</iterate>

Within this I check the value of a property, 'myProperty' and complete the
WHER clause accordingly. The iterate clause now looks like this:

<iterate prepend="AND" property="MyMap.myList" conjunction="AND" open="("
close=")">
    <isNull property="MyMap.myList[].myProperty">
         <!-- code when property is NULL -->
    </isNull>
    <isNotNull property="MyMap.myList[].myProperty">
         <!-- code when property is _not_  NULL -->
    </isNotNull>

</iterate>

When I run this, the error message seems to indicate that my syntax i
nrelation to the List is incorrect:-

--- 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:

If anyone can shed any light as to what I've missed, here, I'd be grateful.

Thanks
