Forms with map of beans with lists of beans... 2007-01-21 - By Dave Newton
Back
...I think I stopped at the right place in the
subject.
I have a map of beans, the beans have a list of other
different beans. I'm struggling to make this work with
the auto-type conversions (various errors depending on
how I set things up; currently getting an NPE, have
gotten many other spectacularly long-winded stack
traces).
I'm wondering if this is doable or if I should just
create accessors in my Action to get to this lists
directly, or if there is some
MyAction-conversion.properties magic I can do to make
it all work.
My current MyAction-conversion.properties file looks,
more or less, like this:
Key_exDataMap=java.lang.Long
Element_exDataMap=foo.ExData
Element_list1=foo.model.TheData
CreateIfNull_list1=true
In the JSP:
<s:textfield
name="exDataMap[%{#exData.id}].list1[0].field1" />
So I have exDataMap = Map<Long, ExData>
ExData has list1 = List<TheData>
TheData has Long field1
Now I know the _list1 stuff is nested within the map,
but something else I did several months ago led me to
believe that it worked (but I might have solved that
some other way; I no longer recall).
TIA,
Dave
