Question

In my class i have a function according to:

public List<String> getDeclaredFields() {
  List<String> fieldList = new ArrayList<String>();

  for(Field field : Equipment.class.getDeclaredFields()){
    if(!field.getName().contains("_") && !field.getName().equals("id") && !field.getName().equals("serialVersionUID") ) {
      fieldList.add(field.getName());
    }
  }
  Collections.sort(fieldList); 
  return fieldList;
}   

which returns a list of strings of all declared fields in the class.

In my facelet file I would like to perform something like:

<c:forEach var="field" items="#{bean.entity.declaredFields}">
  <h:outputText value="#{msg.#{field}}" />
</c:forEach>

However, this will result in errors.

javax.el.ELException: Error Parsing: #{msg.#{field}}

I would like to do this, cause when I do some changes of field(s) in my class, I simply add a variable in my message bundle with the same name as a field. At this way, I dont have to update all my facelet files when modifying fields. Just remove or add new variables in the message bundle file.

Do you have some ideas?

Best regards

Answer 1

you should be able to reference it using [] notation:

#{msg[ field ]}

give that a try
