Subject Indexed properties in tags within iterate
Date Wed, 26 Jan 2005 22:06:02 GMT
Hi,

Is this legal:

<update id="createDynamicTable" parameterClass="dynamicTableDefinition">
CREATE TABLE a_dynamic_table
   <iterate property="columnList" open="(" close=")" conjuction=",">
     $columnList[].name$
       <isEqual property="columnList[].type" compareValue="int">
	INTEGER NULL
       </isEqual>
       <isEqual property="columnList[].type" compareValue="double">
	DOUBLE NULL
       </isEqual>
   </iterate>
</update>

As you might expect, I'm trying to build a dynamic table from a 
java.util.List of beans each with a "name" and "type" property.

Currently, I'm getting an expection when iBatis (2.0.9) is trying to 
access the "columnList[].type" value in the isEqual tag. Is this sort of 
construct legal?

Thanks,
Philippe

Here are parts of the stacktrace that might be helpful:

[...]
--- The error occurred in dynamicTable.xml.
--- The error occurred while preparing the mapped statement for execution.
--- Check the createDynamicTable.
--- Check the parameter map.
