how-to change default submodule within module? [message #902943]

Hello Group Members,

I have modules with certain submodules within the navigation part on the left side of the Riena application.
Default-wise when i click on / open a module, the view backing the first submodule is opened.

But in one case i want to change this default behavior and have the second submodule selected on opening the module thus opening corresponding view for it.

Since I didn't find a solution anywhere, is it possible at all?
If yes, how can i accomplish it?

Thanks,
Chris

Hello Chris,

you can write your own ModuleController that implements your wanted functionality.
Inside your ModuleController-implementation you can add a listener to the node of the module and after the module is activated you can activate another sub-module.

Here is a very simple example:

private class Second extends SWTModuleController {
	public Second(final IModuleNode navigationNode) {
	super(navigationNode);
		navigationNode.addListener(new ModuleNodeListener() {
		@Override
		public void afterActivated(final IModuleNode source) {
			super.afterActivated(source);
			final List<ISubModuleNode> children = source.getChildren();
			if (children.size() >= 1) {
				children.get(1).activate();
			}
		}
	});
}

(Note: Extend SWTModuleController and not ModuleController)

You must add your new ModuleController to the ModuleNode.

Example:

IModuleNode playgroundModule = new ModuleNode(new NavigationNodeId("playgroundModule"), "Playground");
playgroundModule.setNavigationNodeController(new Second(playgroundModule));

This will only works, if you uses NavigationAssembler. It isn't possible with the assemblies2 extension points (org.eclipse.riena.navigation.assemblies2).

I hope this explanation helps to solve your problem.

Greetings,
Thorsten

Thank you very much for this solution and your quick answer, Thorsten.

Unfortunately we are using assembly2 since we have several modules representing business partners.
Is there an alternate solution for assembly2?
Is it possible to replace NavigationProcessor and would that lead to a solution?

Best regards,
Chris

FYI,

unexpectedly I could use your solution since I had access to the ModuleNodes when they are constructed.

So thank you very much again,
Chris
