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?
