Description

A simple component:

@SupportsInformalParameters
public class Img {

@Inject
private ComponentResources resources;

@Parameter(autoconnect = true, defaultPrefix = BindingConstants.CONTEXT)
private Asset src;

boolean beginRender(MarkupWriter writer)

{ writer.element("img", "src", src); resources.renderInformalParameters(writer); writer.end(); return true; }

}

Fails on:

<t:img src="images/stripe.gif" width="984" height="18" alt="" />

With:

Parameter 'alt' must have a non-empty binding.
