ContactItemHandler Question

Hi All,

I’‘ve experimenting with the ContactItemHandler and I’‘ve run across a problem that has left me a bit stumped. As you can see from the code below I’‘ve added a ContactItemHandler (via the initContactHandlers() method) that shows a dialog whenever one of contacts presence changes, however the dialog never appears. However, if I “drop-down” and start working with the Smack directly (via the initContactHandlers2() method) the dialog appears whenever the user presence changes. I’‘d prefer to keep working with the Spark API if at all possible so I’'m wondering if there is a problem with my Spark code or if there is an issue with Spark?

Thanks,

Ryan

Hi Ryan,

Are you sure the presence of the contact item is changing? I’'m using this code directly as well and it is working fine. Have you tried just adding a default listener?

ex.

contactItem.setHandler(new ContactItemHandler() {

public void handlePresence(Presence presence) {

// Do nothing unless offline.

if (presence == null) {

contactItem.setIcon(null);

}

}

public boolean handleDoubleClick() {

// Retrieve dataform and display.

try {

showWorkgroup(contactItem);

}

catch (Exception e) {

e.printStackTrace();

}

return true;

}

});

Hi Derek,

You were right, it turned out to be a client issue - I had the exact same though occur to me while I was driving home thought a snow storm last night.

Thanks for the reply,

Ryan

Hi Ryan,

I wonder why you did post your question here, very uncommon that dev’'s use a public forum Or are you more someone like an external dev?

LG

Hi LG,

I know, it’'s crazy that a developer has to ask for help.

I do not work for Jive, rather I was made a developer in recognition of my involvement in the Jivesoftware.org community both in terms of my participation on these forums and code I’‘ve contributed. For a long time I’‘ve been interested in the software that helps build communities, forums, IM, wiki’‘s, etc., so I’'m real excited to be part of the Wildfire project.

Unfortunately, since I haven’‘t yet figured out a way to turn this sort of work into a paying, full-time job I’‘ve been working on some other projects (some related) so my participation here has dropped off somewhat while my list of things I want to do continues to grow. Hopefully my schedule will soon clear up a bit and I’'ll be able to jump in some more.

Cheers,

Ryan
