9:22 a.m.
I was writting the code for and app to add a record to the database:
(I've translated the code from spanish, asume the code has no typo)
this is a form to add a currency, the currency has a country mapped to it.
The xhtml form uses a tempate with <s:vallidateAll>
Here the monedaNueva.xhtml:

|
| </h:selectOneMenu>
|
| </s:decorate>
| ...
And an error came out:
| Conversion Error setting value ....Country@qw12... 'null Converter'.
|
So I've added the <s:convertEntity /> under the <s:selectItems line:
| ...
| <s:decorate template="edit.xhtml">
| <ui:define name="label">
| <label jsfc="h:outputLabel" for="country"
value="#{m['E_COUNTRY']}"></label>
| </ui:define>
|
| <h:selectOneMenu id="country"
value="#{currency.country}">
| <s:selectItems value="#{countryList}"
var="aCountry" label="#{aContry.name}" />
| <s:convertEntity />
| </h:selectOneMenu>
|
| </s:decorate>
| ...
After I've added the <s:convertEntity /> I try enter the xhtml page and the
following error comes out:
| com.sun.facelets.tag.TagException: /monedaNueva.xhtml @55,48 <s:convertEntity>
