Hello Bernd,
thank you for your hints. I implemented the converter class IntegerConverter
(hopefully I did choose the right Interface (javax.faces.convert.Converter)
My IDE already tells me that converter-id and converter-class are not allowed
here.
Thus the converter does not work in Tomcat.
I pasted the error output from Tomcat further down. A verbatim tag ist
suggested. However that did not help either.
You also mentioned a message tag (<tc:messages />). Can I place it anywhere in
the file?
What is wrong with my converter tag?
<tc:selectOneChoice value="#{myBean.userOption}"
valueChangeListener="#{maintenance.changeUserSelectedStatus}"
id="userGroupChoice">
<f:selectItems value="#{maintenance.userOptionItems}" id="userChoiceItems"/>
<converter>
<converter-id>com.test.converter.IntegerConverter</converter-id>
<converter-class>com.test.converter.IntegerConverter</converter-class>
</converter>
<f:facet name="change">
<tc:command />
</f:facet>
</tc:selectOneChoice>
-- the converter class:
package com.test.converter;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.ConverterException;
import javax.faces.convert.Converter;
import org.apache.log4j.Logger;
public class IntegerConverter implements Converter {
/** Log4j-Protokolierer */
private Logger log = Logger.getLogger(this.getClass().getName());
public Object getAsObject(FacesContext context, UIComponent component, String
value) throws ConverterException {
log.info("getAsObject " + value);
return new Integer(value);
}
public String getAsString(FacesContext context, UIComponent
component, Object value) throws ConverterException {
log.info("getAsString " + value);
return value.toString();
}
}
Tomcat output:
17.01.2007 08:48:06 BodyContent should be empty. Component with id _idJsp67 clas
s org.apache.myfaces.tobago.component.UIPanel content
<converter>
<converter-id>com.test.converter.IntegerConverter</converter-id>
<converter-class>com.test.converter.IntegerConverter</converter-class>
</converter>
Please use the f:verbatim tag for nested content!
Regards
Clemens
