Hi,

1. I am building a small rcp application based on pure e4 to learn the new paradigms. I have build an application with Application.e4xmi in one bundle and a fragment.e4xmi in another. The Application.e4xmi has a perspectivestack and the fragment.e4xmi hooks with a perspective into this stack. In the fragment I have a part with a pojo view und added to the part in the menus section some popupmenus. The menuitems are connected with pojo handlers. When I start the app before the main window shows up, every popup menu handler is executed. Do I missing something?

2. In my fragment.e4xmi under the part I do not find a toolbar section (a view toolbar). How do I add a toolbar to a part in *.e4.xmi?

Thank you

Christian

Ad 2: is resolved: Just check the checkbox "toolbar" in part section.

Hi Christian,

I have a setup that is very similar to yours without the problems you mentioned. When you debug your code (put a break-point in @Execute of a Handler) and go back until you find ContextInjectionFactory.invoke(contrib.getObject(), Execute.class, lclContext) where does this get called?

Greetings
Christoph

Ad 1: When I select an entry in the table of the view, any registered handler executes too. What am I doing wrong?

Hi Christoph,

There is no ContextInjectionFactory.invoke, there is a Method.invoke and aContextInjectionFactory.make. I attach a screenshot of the debug output.

Thank you!

Can you show us your Handler? In handlers you don't use @Inject, I guess
your handler is written wrong and looks like this:

@Execute
@Inject
void handle() {
}

which is wrong and should look like this:

@Execute
void handle() {
}

The call comes from the processHierarchy call which doesn't run the @Execute. I plan to remove the processHierarchy once and for all in https://bugs.eclipse.org/bugs/show_bug.cgi?id=376254

You are right, Tom, that was the problem. I removed the @Inject annotation and everything works ok! Thank you!

This would not have solved the problem because at a given point we need
to create an instance of the handler and then we would have called the
method annotated with @Inject ;-)

I never said the bug solves the problem, I just referenced the bug so that in the future it won't be needed to be called as (as stated in the bug) people are using it already in their POJOs.

And IIRC the processHirerarchy itself (and so will my addon) called the @Inject as part of the call to the ICF.create so Kudos for spotting that Smile
