Informal Parameters are not allowed to have the value "" (the empty string)
---------------------------------------------------------------------------
Key: TAP5-845
URL: https://issues.apache.org/jira/browse/TAP5-845
Project: Tapestry 5
Issue Type: Bug
Components: tapestry-core
Affects Versions: 5.2.0.0
Reporter: Howard M. Lewis Ship
Priority: Minor
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.
