Yes, I've done all the tests, and really doesn't work.
If someone need to use 1:1 optional (or 1:0..1), cannot use proxy. But it's
not a lose performance scenario (at least for me), since it's 1:0..1 only...
If someone could double check it, please do... It's a boring bug that can
affect others trying to use proxies with 1:0..1 mappings.
Best regards,

Subject: Proxies && 1:1 optional doesn't work?
Hi! I'm using RC4 CVS Head (I get the source today, at 18:00 GMT-3).
Look sample bellow. If I make OutrasInformacoes dynamic proxy, I get an
error (method getXxx in object null) if Pessoa hasn't a db record in
TB_OUTRAS_INFORMACOES. Also, where there is no OutrasInformacoes em Pessoa,
when I use proxy=dynamic for OutrasInformacoes, executing
pessoa.getOutrasInformacoes==null results in false (in real, it's a proxy,
so it isn't null). But if there is no record, it shouldn't be a proxy. This
should be just null. If I remove "proxy=dynamic" line, the every thing works
fine.
<class-descriptor
class="OutrasInformacoes"
proxy="dynamic"
schema="MGR"
table="TB_OUTRAS_INFORMACOES">
<field-descriptor
name="codigoPessoa"
column="CO_PESSOA"
jdbc-type="INTEGER"
primarykey="true"
autoincrement="false" />
<reference-descriptor
name="pessoa"
proxy="false"
class-ref="br.com.mgr.beans.PessoaFJBean">
<foreignkey field-ref="codigoPessoa"/>
</reference-descriptor>
</class-descriptor>
<class-descriptor
class="Pessoa"
proxy="dynamic"
schema="MGR"
table="TB_PESSOA">
<field-descriptor
name="codigo"
column="CO_PESSOA"
jdbc-type="INTEGER"
primarykey="true"
sequence-name="SQ_PESSOA"
autoincrement="true" />
<reference-descriptor
name="outrasInformacoes"
proxy="true"
class-ref="br.com.mgr.beans.OutrasInformacoesBean">
<foreignkey field-ref="codigo"/>
</reference-descriptor>
</class-descriptor>
