Exception: BeanUtils.populate

[Leandro Carvalho]

Hi,
I'm having this exception: javax.servlet.ServletException: BeanUtils.populate
When I try to submit a JSP like this:

<table width="458" border="0" cellpadding="0" cellspacing="0">
<html:form action="/salvarTipoNaturezaOperacao">
<tr class="even" height="15px">
<td width="229" height="25"> 
<html:text property="tpnatope.descricao" size="38"/>
</td>
</tr>
</html:form>
</table>

(This is a small version that reproduces the same error of the original code)

And the Action Form is like this:

public class TipoNaturezaOperacaoForm extends ValidatorForm {
private static final long serialVersionUID = 1L;
private TpNatOpeVO tpnatope;

public TpNatOpeVO getTpnatope() {
return tpnatope;
}
public void setTpnatope(TpNatOpeVO tpnatope) {
this.tpnatope = tpnatope;
}
}

And this class, TpNatOpeVO, looks like:

public class TpNatOpeVO implements java.io.Serializable {
private static final long serialVersionUID = 5425768733903404538L;
private String descricao;
 
public String getDescricao() {
return this.descricao;
}
 
public void setDescricao(String descricao) {
this.descricao = descricao;
}
}

Can anyone help me? More information needed??

Thanks in advance...

Bom Dia, Leandro:

I see one problem which may just be your effort to translate the application into English. The line

<html:text property="tpnatope.description" size="38"/>

should read

<html:text property="tpnatope.descricao" size="38"/>

This problem could also occur if the tpnatope property of your ActionForm is null. Can you verify that it has a value?

I changed the scope from request to session and worked... :/

Thanks anyway!

Edit:
Boa tarde, Merrill...

It was a miss spelling, because I was thinking about translate the portuguese words to english and I changed my mind...
Thanks!
