hi Arnaud,
if i follow the approach of the mapping file,
but i am having problems in understanding it.
Ok, according to the docs and to what u said, i must
define my SimpleAttribute as follows, right?
..
<class name="test.FList">
<field name="SimpleAttribute" collection="hashtable"/>
<field name="CollectionAttribute" collection="hashtable" />
</class>
but i am missing some points: how can i then retrieve
the following SimpleAttribute
<SimpleAttribute>
<name>foo</name>
<value>foobar</value>
</SimpleAttribute>
?? if my class was generated thru SourceGenerator, i won't have
any put/get method for SimpleAttribute.
Somewhere i am missing something... can u give me some hints??
thanx in advance and regards
marco
