Hi again,
I discover debugging my application that the error is in the moment on tag
s:select renders it at JSP.
I change my code to:
<s:select name="filtroRegiao" list="todasRegioes" listKey="id"
listValue="descricao" headerKey="-1" headerValue=" "
value="%{filtroRegiao.toString()}"/>
and works!!!
But in the first time when I enter in the page, filtroRegiao is null and in
my console appears:
WARNING: Caught an exception while evaluating expression
'filtroRegiao.toString()' against value stack
java.lang.NullPointerException: target is null for method toString
Anyone have tips for me?
Thanks,
Alexandre Lima

Subject: [S2] Tag select have problems
Hi everyone,
I got last version Struts 2.0.3 today and updated now my application but
one page is gone wrong.
In this page, I have the code:
<s:select name="filtroRegiao" list="todasRegioes" listKey="id"
listValue="descricao" headerKey="-1" headerValue=" " />
My Action class have two atributes: todasRegioes is a java.util.List and
filtroRegiao is a java.lang.String. The list todasRegioes have
instances from class Regiao which have atributes id and descricao.
When I submitted my form to same page for refresh it, the select doesn't
show the value selected, always show the value setting in headerKey.
Anyone can help me?
Alexandre Lima
