where to do the remote service call [message #26143] Sun, 17 May 2009 19:14 Go to next message

Originally posted by: kessels.sjoerd.gmail.com

Hi,

I have a view and corresponding controller that displays a list of projects.
In the controller's configureRidgets() method I placed the call to the
remote service that returns the list of projects. This works.
However the second time I open the view via the navigation menu the
configureRidgets() method is not called anymore, which makes sense. So my
view is not repopulated.

What would be the best place to place my remote service call so I am able to
call it every time the view (navigationnode) gets activated while still
being able to ge to the controller to update the model that is bound to the
table?

Is there something like a listener of navigationnodes? And where would I
place the listener?

Thanks,

Sjoerd

Hi Sjoerd,

you can add to every node of the navigation a listener
(NavigationNodeListener).
So you will be informed after every change of status of the navigation node.

example:


@Override
public void setNavigationNode(ISubModuleNode navigationNode) {

super.setNavigationNode(navigationNode);

getNavigationNode().addListener(new SubModuleNodeListener() {
@Override
public void afterDeactivated(ISubModuleNode source) {
super.afterDeactivated(source);
getStatusLine().clear();
}
});
}

greetings

Thorsten

Hi Sjoerd,

you can use the NavigationNodeListener for a number of different event you get for the nodes. For the problem that you
describe you might as well overwrite the method afterBind in the SubModuleController (make sure you call
super.afterBind()) and that method "afterBind" gets called each and every time that SubModule is activated.

cheers
