Hello,
I'm trying to use Common Navigator Framework in my Project
I used Template "Common Navigator View" from org.eclipse.ui.navigator.viewer and everything would be fine but the navigator is empty (doesn't contain resources) unless i right-click on the view.

Could you help me solving this issue?

Thanks a lot.

If you follow these instructions you should be able to get what you need:

Thanks for your answer.

Francis I followed this instruction and I have the same problem.

I turned on tracing and after application is started, when i right-click on (empty) navigator, then data is initialized (just like it weren't initialized automatically).

Trace output:

Application Started: 44265 <------ AFTER THIS I RIGHT-CLICKED ON NAVIGATOR

...

Just like it was normal that it is initialized lazily...

After further investigation I found that
CommonNavigator.getInitialInput (which was returning getSite().getPage().getInput()) was returning null (instead of workspace root).

I saw that there is an information that WorkbenchWindowAdvisor should have getDefaultPageInput overridden but it isn't called from workspace.

Any thoughts?

I'm thinking you don't have an RCP application, that instead you are using the CN in a set of plugins that you install into an Eclipse environment? Is that correct? The WorkbenchWindowAdvisor is only used for an RCP application.

If you are not using an RCP application, then you should make a subclass of the CommonNavigator class and override getInitialInput() to point to the workspace root.

We have the same problem; our CNF view is not rendering initially. We are using a launch config that points to our RCP product backed by our application but the WorkbenchWindowAdvisor#getDefaultPageInput is not being called. What could we be doing wrong?
