Hi,
I have created an e4 application project using the respective template. Starting the application from pde is ok. When I try to start with -console as program argument (added the felix gogo bundles an the equinox.console bundle) the osgi prompt shows up but the application window does get visible until I fired one or several ss commands in the console. Am I missing something?

Probably

. What bundles o you have marked for autostart? See:

Hi,

I did not have any auto-starts and run-levels set. After setting them as described in the target of the link nothing changed: I have to write "ss" to let pop up the main window. Are there other bundles that have to be set in configuration? Without -console set, the application starts normally.

Hi Christian

I don't know if this is what you want, but with the VM Argument -Dosgi.console.enable.builtin=true you do not need the equinox.console and felix bundles. This is the way I use it, but I just use it to question the bundle states (ss) during runtime, so I don't need the new fancy features.

Greetings
Christoph

Hi Christoph,

I have now removed the dependencies to the felix.gogo and the equinox.console bundles and added the -Dosgi.console.enable.builtin=true argument. There is no osgi-prompt in the console and calling e.g. "help" from it does nothing.

Also I have a perspective-stack with a selected perspective, that contains a (also selected) partsashcontainer, containing a (selected) part-stack, containing a (selected) part with an injected composite containing a label with text Hello (with focus set to it. The whole application window is empty. There are the template menues but the components are not shown... The whole is on a Windows XP machine running jre7 runtime and eclipse 4 m5a.

Hi Christian

this is what my Arguments look like in the .product file I use to start the (pure E4) application from the IDE:

<launcherArgs>
      <programArgs>
-console
-debug</programArgs>
      <vmArgs>-Dosgi.console.enable.builtin=true</vmArgs>
</launcherArgs>

Concerning your other problem: This could be an issue with the saved model state. Do you have "Clear workspace" activated in your Run Configuration? Alternativly you could add -clearPersistedState to your programm arguments to make sure, that the model is recalculated on startup.

Another way to debug is to add *.e4.tools.emf.liveditor (and required bundles) to your configuration. You can then check your model at runtime with Alt+Shift+F9.

Greetings
Christoph

BTW: I also don't see an osgi prompt at first, but when you put the focus in the console and just type the command it will work and show the prompt afterwards.

Hi Christoph,

sorry for the late answer. I have been in Holidays and I am back now. Thanks to your help I can now start the example. But I have another issue now: The method of @PostConstruct is not called, so I get an NullPointerException in the method annotated with @Focus. I am not sure, if I were a bit thumb. The tutorials seem not to have those problems at all. Sorry for that!

Thank you very much!

Christian

Hi Christian

that happens when DI can not find all the parameters in the context that are needed to call the method. To try if that is the case you can annotate every parameter with @Optional and then see which one is null.

Hope that helps.

I thought objects whose @PostConstruct fails (because of unsatisfied parameters) leads to an InjectionException and the object creation fails. But I may be wrong.

This problem can happen if your bundle is resolving to a different version of @PostConstruct than that used by the injector. Be sure to import package javax.inject 1.0.0.

Brian.

You are correct. Thanks for the correction! This does lead to an InjectionException. I confused this with Handlers: If a parameter in @Execute or @CanExecute can't be resolved, there is no exception ... it just doesn't happen.

Hi Christoph,

I have no parameters in the code. The code of the part is:


package ch.eugster.colibri.parts;

import javax.annotation.PostConstruct;
import javax.inject.Inject;

import org.eclipse.e4.ui.di.Focus;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Label;

public class Part 
{
	@Inject
	private Composite composite;
	
	private Label label;
	
	@Inject
	public Part() 
	{
	}
	
	@PostConstruct
	public void postConstruct() 
	{
		composite.setLayout(new GridLayout());
		label = new Label(composite, SWT.None);
		label.setLayoutData(new GridData(GridData.FILL_BOTH));
		label.setText("Hallo");
	}
	
	
	
	@Focus
	public void onFocus() 
	{
		label.setFocus();
	}
	
	
}

and the exceptions thrown are:

Hi Christian,

I don't know why postConstruct is not called on your part. I think you should open a new topic, so that others will read it and might have tipps on where to look.

Christian -- sounds suspiciosly like you're missing versions on your import-packages. See the following for details (recently updated):
