s:convertEntity not working properly

bashan Aug 21, 2008 6:36 PM

Hi,

I am having a strange problem with convertEntity. My page is loaded properly, but when I am viewing the source of the page I see that the generated ids for each option tag does not match the ids in my database. Currently I have in my database 3 items. The ids are: 1,2,3. In the dropdow, the generated ids are: 0,1,2.

Here is the dropdown code:

<t:selectOneMenu id="channel" value="#{upload.selectedChannel}" required="true" forceId="true"
                             immediate="true">
              <a4j:support event="onchange" reRender="subChannel" />
              <s:selectItems value="#{upload.channels}"
                             var="channel"
                             label="#{channel.name}"
                             noSelectionLabel="-- Select Channel --"/>
               <s:convertEntity />
            </t:selectOneMenu>

Here is the generated html with the wrong ids:

<select id="formUpload:channel" name="formUpload:channel" size="1">      <option value="org.jboss.seam.ui.NoSelectionConverter.noSelectionValue">-- Select Channel --</option>

        <option value="0">News/Events</option>
        <option value="1">Product Reviews</option>
        <option value="2">How To</option>
</select>

The generated ids won't match up unless you make them, see: http://in.relation.to/Bloggers/SselectItemsCustomisingTheValue for how to do this.

Thanks, I got the point.

I wrote this class:

@Name("org.jboss.seam.ui.entityIdentifierStore")
@Scope(ScopeType.PAGE)
public class CustomEntityIdentifierStore extends EntityIdentifierStore
{
  public String put(Identifier identifier, Object entity)
  {
    if (entity instanceof Channel)
    {
      Channel channel = (Channel)entity;
      return "channel:" + channel.getChannelId();
    }
    else
    {
      return super.put(identifier, entity);
    }
  }

 public Identifier get(String key)
 {
    if (key.startsWith("channel"))
    {
      String id = key.substring(7, key.length());
      return new EntityIdentifier(Channel.class, new Integer(id));
    }
    else
    {
      return super.get(key);
    }
  }
}

But it seems like Seam doesn't take it, cause it doesn't stop in breakpoints.
In addition when navigating to this page I get the exception (which obviously caused since component is not taken...):
