Order of rendering components
Hi,
While creating a FAQ page, I made a component that takes a Title + a
Body, then render it with a counter in the page for the FAQ number.
Adding a FAQ is as simple as writing:
<span jwcid="@FaqIten" title="The title">
This is the body of this FAQ item
</span>
But then I'd like a FAQ summary, taking all titles of all the FaqItems
and put them at the *beginning* of the page. So each FaqItem would
register its title in a collection in the page and then the FaqSummary
component take that collection and render it as a Summary.
My problem is how to make the FaqSummary render itself *after* all the
FaqItem are rendered?
Thanks

This is indeed a good solution! Could you send me a snippet of code for
enumerating all FaqItems?
Thanks

First my q: couldn't you use an easier solution?
For example:
- enumerating all FaqItem components in the page (or in the body of
FaqSummary), and getting the title values from their parameters?
This solution is somewhat easier to implement if you do not need fully
flexible component hierarchy (I mean for example FaqItems are rendered
from multiple pages).
- if data of FaqItems come from a database, you can use the same query
to fill the FaqSummary
- etc :)

Thanks a lot, that makes sense.
But where do I put what?
I'll have something like:
<span jwcid="@FaqSummary"/>
<span jwcid="@FaqItem" title="title1">
Body of FAQ #1
</span>
<span jwcid="@FaqItem" title="title2">
Body of FAQ #2
</span>
Where do I put the Nested thing?

In such advanced cases you can use IMarkupWriter.getNestedWriter():
When rendering the page:
- render all FaqItems to a nested writer
- render the FaqSummary itself
- close() the nested writer (which implicitly commits its content to the
main writer)
