      Description

      I have created a component that looks like this:

      public class HeraldryShieldIMG
      {
      @Parameter(value="64")
      @Property
      private int _width;

      @Parameter(value="76")
      @Property
      private int _height;

      @Parameter(value="literal:Heraldry")
      @Property
      private String _altText;

      @Parameter(required=true)
      private BaseHeraldry _heraldry;

      @Inject
      private ComponentResources _resources;

      @BeginRender
      public void beginRender(MarkupWriter writer)
      {
      Link link = _resources.createPageLink("ShowHeraldryShield", false, new Object[]

      { "shield", _heraldry.getBottom(), _heraldry.getTop(), _heraldry.getPattern(), _heraldry.getIcon(), _width, _height }

      );
      writer.element("img",
      "src", link.toAbsoluteURI()+".png",
      "width", ""+_width,
      "height", ""+_height,
      "alt", _altText);

      _resources.renderInformalParameters(writer);
      }

      @AfterRender
      void afterRender(MarkupWriter writer)

      { writer.end(); }

      }

      Now if I use it like this:

      <t:HeraldryShieldIMG heraldry="page.webUser.userAccount.heraldry" align="middle" />

      in a template I would think that the informal parameter "align" would be rendered into my current "img"-tag. It is not. Neither is "style"/"class"/etc. What did I not do, all the examples I can find with _resources.renderInformalParameters(writer); do nothing special to indicate that they accept informal parameters (at least not what I can see). In tapestry 4.x there was an option indicating if a component accepted informal parameters - how is this decided now?
