Niels Beekman commented on IBATIS-131:
--------------------------------------
I have built iBATIS from the source and tested my code. All works fine, except
when dealing with a 'deeper' iteration, example:
<iterate property="myHashMap.myList">
<isEqual property="myHashMap.myList[].someProperty" compareValue="true">
$myHashMap.myList[].anotherProperty$
</isEqual>
</iterate>
I get the following exception:
Caused by: com.ibatis.common.beans.ProbeException: The 'myHashMap.myList'
property of the java.util.HashMap class is not a List or Array.

I have debugged this some more and it seems that iBATIS does not respect the
dot-notation, it tries to directly get 'myHashMap.myList' from the map instead
of breaking it up (ComplexBeanProbe, line 75).
Hope this helps,
Niels
PS When building from the source using build.xml I get
java.lang.NoClassDefFoundErrors about a couple of Oracle-classes, these are
referenced when accessing the ToplinkDaoTransactionManager-class in the
XmlDaoManagerBuilder-constructor, I had to include these Oracle-classes in the
build.
> Fix use of list[]-notation in propertyattributes of dynamic tags

> Key: IBATIS-131
> URL: http://issues.apache.org/jira/browse/IBATIS-131
> Project: iBatis for Java
> Type: Bug
> Components: SQL Maps
> Environment: All are affected.
> Reporter: Niels Beekman
> Assignee: Brandon Goodin
> Fix For: 2.2.0
>
> When using an iterate-tag to loop a list, one cannot point to the current
> element in attributes of inner tags, for example, the following fails:
> <iterate property="myList">
> <isEqual property="myList[].someProperty" compareValue="true">
> $myList[].anotherProperty$
> </isEqual>
> </iterate>
> iBATIS tries to index the property myList with an empty string, but it should
> use the current element (the []-notation works fine within inner tags), when
> an index is supplied it works just fine...
