Well, a simple implementation here may be like:
public class Decorate {
@Parameter(required = true)
private Object by;
@Inject
private ComponentResources componentResources;
@Inject
private Environment environment;
Object beginRender()
{
environment.push(Block.class, componentResources.getBody());
return by;
}
// in your case, should not render the body, orelse there will be two cases
rendered.
boolean beforeRenderBody() {
return false;
}
}
public class DecoratedBody {
@Inject
private Environment environment;
Object beginRender()
{
return environment.peek(Block.class);
}
}
I've test and it works.
<div t:type="complexcomponent">
<p:titleDecorator>
aaa <t:decoratedBody/> bbb
</p:titleDecorator>
</div>
<div t:type="complexcomponent">
<p:titleDecorator>
<t:pageLink page="index"><t:decoratedBody/></t:pageLink> </p:titleDecorator>
</div>
They all work and show what I need.

I imagine such a solution:
ComplexComponent.java
@Parameter
@Property
Block titleDecorator;
ComplexComponent.tml
<div>
...
a lot of tags and components
...
<t:decorate by="titleDecorator">
<span id="title">
.. complex content ..
</div>
</t:decorate>
...
a lot of other tags and components
...
</div>
Page.tml
<t:complexComponent>
<t:titleDecorator>
<t:pageLink page="otherPage"><t:decoratedBody/></t:pageLink>
</t:titleDecorator>
</t:complexComponent>
Legend:
decorate - component a little bit similar to delagate
<t:decoratedBody/> - special tag like <t:body/> but relative to
containing Block.
It's a pity, that it is only imagination.
Is it possible to do something similar now?
If not, is it technically possible to make such a improvement in
future versions? It would be very powerful feature.
