RE: #foreach and page iterators

Thanks for the comments.

Point taken about using actions - I have started use bean shell scripts but
there is still a problem with the iterators.

The FilePageManager getPages() works only if the page root is supplied in
the call:

import org.jpublish.PageManager;
PageManager pm = site.getPageManager();
Iterator itr = pm.getPages(pm.getRoot() + "/topics/");

but it does not like it if there is a file in the 'topics' sub-directory
which does not have
a '.xml' ending (for example README.txt) - throws a
JPublishRuntimeException: File not found

The XMLPageManager getPages() does not work for me. The returned iterator is
not null but it cannot be used - hasNext() never returns false and next()
throws a JPublishRuntimeException.

I am working with a pages.xml which has entries with the following format:

<page path="/topics/resources">
	<property name="title">Resources</property>
</page>
<page path="/topics/progress">
	<property name="title">Progress</property>
</page>

and a bean shell script as follows:

import org.jpublish.PageManager;
PageManager pm = site.getPageManager();
Iterator itr = pm.getPages("/topics/");

Thanks for any help

Andrew

Florian is correct: it is best to do all logic like this in an action as
opposed to in the
Velocity code.  You will have a lot more flexibility in the action, plus you
can reuse your
code that way.

No, there is nothing right now to have common properties.  I would rather
not put them in
pages.xml though because that file is only used when using the
XMLPageManager.  Or at least
I would first like to come up with a way to do it using the default page
manager.  I'll think
about it for a bit and see where it would best fit.
