Chris Poulsen updated TAP5-2566:
--------------------------------
Summary: RenderInformals mixin does not work with inherited informal
parameters (was: RenderInformals mixin does not work with interited informal
parameters)
> RenderInformals mixin does not work with inherited informal parameters
> ----------------------------------------------------------------------
>
> Key: TAP5-2566
> URL: https://issues.apache.org/jira/browse/TAP5-2566
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.4.1
> Reporter: Chris Poulsen
>
> It seems like the informal parameters are not propagated to the mixin, if
> they are inherited. Explicitly rendering the informals instead works.
> The following example illustrates the issue:
> {code:title=Page.tml}
> ...
> <t1 inheritedInformal="inheritedInformal"/>
> ...
> {code}
> {code:title=T1.java}
> @SupportsInformalParameters
> public class T1
> {
> @Component( inheritInformalParameters = true )
> private T2 t2;
> }
> {code}
> {code:title=T1.tml}
> <div xmlns:t="http://tapestry.apache.org/schema/tapestry_5_4.xsd";>
> <t:content>
> <span t1="t1">
> <span t:id="t2"/>
> </span>
> </t:content>
> </div>
> {code}
> {code:title=T2.java}
> public class T2
> {
> @Mixin
> private RenderInformals renderInformals; // Does not work like expected
> @BeginRender
> void begin( MarkupWriter writer )
> {
> writer.element( "span", "t2", "t2" );
> // resources.renderInformalParameters( writer ); // Works like
> expected
> }
> @AfterRender
> void after( MarkupWriter writer )
> {
> writer.end();
> }
> @Inject
> private ComponentResources resources;
> }
> {code}
> The expected output should be:
> {code}
> <span t1="t1">
> <span inheritedinformal="inheritedInformal" t2="t2"></span>
> </span>
> {code}
> But the produced output is:
> {code}
> <span t1="t1">
> <span t2="t2"></span>
> </span>
> {code}
> The problem have arisen because we wrap the tapestry Radio component (which
> uses the RenderInformals mixin)
> A workaround could be to use the RenderNotification plugin and explicitly
> render the informals in the parent component (T1 in the sample) - but that is
> not really a nice "solution" (or expected behavior)
