Hi,

I am a Tapestry beginner. I am far from knowing all the internals. I use the PageLink component in one of my as follows:

@Component(id="backLink",
parameters={
  "page=${backLink}",
  "context=backLinkContext",
  "anchor=${prev.getUniqueIdentifier()}"})
private PageLink backLink;

My question is now

What does the ${...} do?

I fail to see what this means: If I replace "context=prop:backLinkContext" with "context=${backLinkContext}" I get a different link than expected. If I replace "page=prop:backLink" with "page=${backLink}" I get no different link. Why?

Kai
