Displaying News in the Index page

[k-dub]

I would like to have news stories in the lower half of my index page. How can I do that? Is it possible?

No I am not building from source, I downloaded rel 1.0. I moved the bean script into the deploy directory and recieved the following error on startup:

I am going to try removing the beanscript (as I assume it has already run) and restart nukes.

Could you file a bur report in sourceforge for this ?

[julien1]

This feature does not exist (yet)

[cnovara]

I have implemented this feature. Want you more details ?

[julien1]

yes

How to implement news stories in the half part of index page.

More precisely, I wanted to see all news on index page (main page), and some news filtered by topic on some "sub index", in fact headers pages.

I modified HtmlModule, to invoke news module, adding the following at the end of
private void print(Page page, String fileId, String contentType, String content, Integer id) method :

try
{
server.invoke(ObjectNameFactory.create "nukes.modules:name=news"), "news", new Object[]{page}, new String[]{Page.class.getName()});
}
catch (Exception e)
{
page.print("Error loading news");
e.printStackTrace();
}

(of course error message should be localized ! :))

The question is : when should we call news ? surely not on each page !

So I choose to trigger if page=index (main page) OR if topicid is not null (ie the address looks like .../nukes/subindex?topicid=2)
Thus, all calls to index page remains unchanged, while I can view stories whenever by completing topicid.

Here is the code snippet for this basic behaviour implementation :

if ("/index".equals(fileId) || page.getParameter ("topicid")!=null)
{
try
{
server.invoke(ObjectNameFactory.create("nukes.modules:name=news"), "news", new Object[]{page}, new String[]{Page.class.getName()});
}
catch (Exception e)
{
page.print("Error loading news");
e.printStackTrace();
}
}

I made that (quick and dirty) to meet my own needs,
to be really usable, IMHO, we should add :
A MBean property (default to NO) to view news or not on index page ;
A topicid meaning "all news" (topicid=0) to view all news in wichever page ;
Localization of error message.
