I want to be able to pass a component (by name, or by reference) into

component I put into a container component.
Let's say I have a ContainerComponent, and at runtime I want to decide
if I render a ContentComponentA, or a ContentComponentB into the
container, how do I do that?
I have tried to put variables into the .tml file to determine the type
from a variable in the java class like so: <div t:type=${aType}/>, and
that does not work.
The structure of Tapestry templates is strictly static, so this is
expected.
It can be done with t:if, but that seems very limiting:
<t:if test="ContentComponentA">
<div t:type="ContentComponentA"/>
</t:if>
<t:if test="ContentComponentB">
<div t:type="ContentComponentB"/>
</t:if>
It would be nice if it could be done via formal parameters, or
programmatically from the Java side, but I haven't been able to figure
it out.
What is the recommended way of doing this?
