hi,i think i maybe like this:when you set a var attribute on the iterator,i
was saved under top level in the ActionContext object,which contains
ValueStack,parameters,attr,etc.
and when you refer the value using OGNL later,you have to specify the data
objects that you're refering,which by default is valuestack. you can specify
#service or #attr.service. The attr will find any value match the name you
specified throughout
the ActionContext.
note that i am not really familiar with it,i hope it will do
some help.
