Title: Capability to use dynamic sql within iterates

You can download the last version of iBatis from CVS. The problem might already be solved.

 

If this doesn't work, take a look at issue 281. This may patch your problem.

I did some further testing after reading issue 131 http://issues.apache.org/jira/browse/IBATIS-131

 

I found that <isEqual> and <isNotEqual> tags work in this situation but other tags like <isNotNull> do not work.  Has anybody got the <isNotNull> tag to work in the sistuation below?

 

Thanks,

Paul

Hello
I have read Issue 148 and it looks like I can use dynamic sql within an iterate tag
http://issues.apache.org/jira/browse/IBATIS-148

I have a problem when I set the property on a tag to be a value on the iterated object.  See "myListOfGooObjects[].id" the below sql.

        <select id="testIterate" resultClass="java.util.HashMap" parameterClass="Foo">
                select *
                from foo
                WHERE  
                <iterate property="myListOfGooObjects" conjunction="AND" >
                         EXISTS ( SELECT 1
                                          FROM bla
                                          WHERE bla.type = 'X' 
                                                <isNotNull property="myListOfGooObjects[].id">
                                                and ( id = #myListOfGooObjects[].id#  )
                                                </isNotNull>
                                        )                      
                </iterate>
        </select>

Here is the parameter classes used,  getters and setters ommited.
class Foo {
    // Contains a list of Goo objects
    List myListOfGooObjects; 
}

class Goo {
    // This is the value that is want to the <idNotNull> tag on.
    Integer id;
}

The error is get is:
--- 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: ""
