Howard M. Lewis Ship updated TAPESTRY-2340:
-------------------------------------------
Summary: Documentation about informal parameters should reference the
@SupportsInformalParameters annotation specifically (was: Informal Parameters
are not rendered in component generating "img" element)

>
> Key: TAPESTRY-2340
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2340
> Project: Tapestry
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.0.11
> Environment: Tomcat server 5.5 on Ubuntu Linux.
> Reporter: Emanuel Greisen
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> 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?
