dynamic messages

[tszpinda]

Hi,

Could anyone tell me if it's possible to do something like:

<h:dataTable var="item" value="#{orderList.resultList}">
  <h:column>
    <h:outputText value="#{messages['#{item.status}']}" />
  </h:column>
</h:dataTable>

Thank you,

Tomek

The following should work:

<h:dataTable var="item" value="#{orderList.resultList}">
  <h:column>
    <h:outputText value="#{messages[item.status]}" />
  </h:column>
</h:dataTable>

For me it renders nothing just empty column. Even if there is no entry in the messages*.properties file.

hi,
what Vladimir said is the proper syntax. I use it in plenty of places of mu application and it works.
Check if you have an entry for the value of item.status in your messages properties file.
And remember that an entry called item.status in the properties file will not work.
Try to display item.status value this way

  <h:column>
    <h:outputText value="#{messages[item.status]}" />
  </h:column>
  <h:column>
    #{item.status}
  </h:column>

Check if both columns are empty. If the second is empty of course the first would be empty as well.In that case debug or check the database to find out why is that value empty. If empty.status has a value,  for instance btw you should have an entry in the properties. For example

btw=By the way

Hope this has helps you!

It's done exactly as you both say.

I think I know what is the problem, item.status is defined as enum, cos I tried with other types like String and it's fine.

[tszpinda]

Does it work for anyone with enums? I think it would be quite useful if it does.

I got something like:

@Entity
public class Order{
   public String code;
   public Status status;

   public enum Status{
      NEW_ORDER(1),
      ALLOCATED(2);
       
      private intValue;

      private Status(int value){
          this.intValue = value;
      }
   }
}

and then

<h:dataTable var="item" value="#{orderList.resultList}">
  <h:column>
    <h:outputText value="#{messages[item.status]}" />
    <h:outputText value="#{item.status}" /> <!-- this works fine -->
  </h:column>
</h:dataTable>

anyone? please :)

[vladimir.kovalyuk]

try item.status.name() and place properties NEW_ORDER and ALLOCATED into your messages.properties

[tszpinda]

Only the way I could get around the problem was adding the method getName() to enum. After that everything works fine.

Thanks guys for help!
