> I found a bug in the select tag.  After debugging the selectmap.jsp a bit, I also have a fix.
> In my UI, I create a select tag on an array of objects and want to display their type.
> <ui:select label="'Action'" name="'actionType'" list="myobjects" listKey="'type'" listValue="'type'" />
> My objects basically look like this:
> public class MyObject {
>     public String getType();
>     public String[] getParameters();
> }
> In the select tag, it has an iterator over the list that basically looks like:
> <webwork:iterator value="parameters['list']">
>     <webwork:property value="{parameters['listKey']}"/>
> </webwork:iterator>
> This fails to display the correct result because the current object on the stack (an instance of MyObject) has a getParameters() method which is incorrectly being called.  
> The fix is to make it use the correct object which is above the current stack pointer (i.e. adding a '../'):
> <webwork:iterator value="../parameters['list']"> 
>     <webwork:property value="{../parameters['listKey']}"/>
> </webwork:iterator>
> This is a problem in the selectmap.jsp, radiomap.jsp, and anywhere else iterators are used that depend on properties above the element in the iterator.
