Hi Geoff,
Supposedly, the condition is a bit complex that requires logic checking be done
programmatically via code, eg. some business rules and database access to reach
a decision on whether <PageLink A> should be rendered. Then, how should I code
it in the renderComponent() body? What I am suggesting to do is have
writer.begin("li") and then getComponent and render, finally writer.end(). But
if this is the case, the static tags and content in the component template
would be meaningless since I am producing it from writer.begin().
Any advise? I am not facing this scenario now, but I think I would be in this
situation in the nearby future.
Tks.
