Hi,

This is still logged as a new feature request internally, but is not currently scheduled for a release.

Hi Will,

Any updates on whether pagination is supported for CE?

Thanks!

this worked fine. thanks. I left the statics beans wrapper just in case we needed any other utils. unless all utils require authentication first.

The default constructor for DateUtils looks like this:


public DateUtils() {
        HttpServletRequest request = ServletActionContext.getRequest();
        User user = AuthFactory.getSessionUser(request);
        timeZone = LocaleUtils.getTimeZone(request, user);
        locale = LocaleUtils.getUserLocale(request, user);
    }

and AuthFactory.getSessionUser(request) simply gets the session for the request and checks for an auth token, which is where the NPE is happening from your previous log.

Starting over, we might be able to do this much easier. What if you ignore StringUtils all together. Since you already have a request object and a user, try simply creating a new DateUtils object with the constructor (request, user). Then add that initialized date utils object to your properties in the community everywhere servlet. From the ftl, simply call the method displayFriendly(date). Together, it would look something like this in the loadProperties method of CommunityEverywhereSerlvet:


        properties.put("dateUtils", new DateUtils(request, user));

and in community-everywhere-content.ftl


${dateUtils.displayFriendly(message.modificationDate?date)}

Let me know if that works for you.

Nick,

Right underneath the props being set for the statics there's this call which set the authtoken into

// Get the user's auth token
        AuthToken authToken;
        try {
            authToken = AuthFactory.getAuthToken(request, response);
        }
        catch (UnauthorizedException ue) {
            authToken = AuthFactory.getAnonymousAuthToken();
        }

        JiveContext jiveContext = JiveApplication.getContext(authToken);

        // load the user from the authtoken
        User user = null;
        if (!authToken.isAnonymous()) {
            try {
                user = jiveContext.getUserManager().getUser(authToken.getUserID());
                properties.put("user", user);
            }
            catch (UserNotFoundException e) {
                Log.error(
                        "Could not load user from authToken with userID: " + authToken.getUserID(),
                        e);
            }
        }

into the props bag as well. Is this what date util's is looking for?

You might need to create an auth token and stick it in the session so date utils can be accessed (it's dependent on the user's locale information). You should have the user information in the servlet, so its just a matter of creating a new auth token and sticking it in the session for date utils.

I've added:

// to get a wrapper around the statics
private static BeansWrapper wrapper = new JiveBeansWrapper();

TemplateHashModel staticModels = wrapper.getStaticModels();

properties.put("StringUtils", staticModels.get("com.jivesoftware.util.StringUtils"));

properties.put("statics", BeansWrapper.getDefaultInstance().getStaticModels());

so that we can grab these utils on the template. adding the calls to:

${statics['com.jivesoftware.util.StringUtils']}.
or

${StringUtils.getTimeFromLong(message.modificationDate.time?long, 1)}

throws an error

Caused by: java.lang.NullPointerException
        at com.jivesoftware.base.AuthFactory.getSessionAuthToken(AuthFactory.java:661)
        at com.jivesoftware.base.AuthFactory.getSessionUser(AuthFactory.java:678)
        at com.jivesoftware.util.DateUtils.<init>(DateUtils.java:69)
        at com.jivesoftware.util.StringUtils.getTimeFromLong(StringUtils.java:1583)

I am a currently logged in user. though.. when I remove this call. the comments return correctly.

Can I just replace FreemarkerManager with JiveFreemarkerManager in the servlet?

Ah, yes. StringUtils is a static class that is automatically added to the freemarker context by webwork. Since community everywhere is its own servlet (outside of webwork), it will have to be added to your properties. Check out JiveFreemarkerManager (populateStatics) method to see how this is done. Basically, you will add the static class StringUtils to your model in the loadProperties method. Alternately, you might be able to load it up using the syntax ${statics['com.jivesoftware.util.StringUtils']}.

It complains that StringUtils isn't available to this template. Do I have to add it to the communityeverywhere servlet?

thanks,
