So, I was following the 3 tutorials for RCP I found on the eclipse site.
The last one shows you how to add a view to the perspective and make
it the default and so on:
http://www.eclipse.org/articles/Article-RCP-3/tutorial3.html
However, when I do this, my createInitialLayout is never called and my
application window is never populated with my custom view. As far as I
can tell, neither my custom view nor my custom perspective is being
created by RCP code. I have put breakpoints into the constructors of
both and neither get hit.
I've compared my RCP app to the example app and I can find nothing
wrong. I've also tested the the example RCP app, and despite showing
the view 'properly', my breakpoint in that application's
createInitialLayout is never hit either. I am highly confused. Is
there some new way to set this up in eclipse 3.1.x? I noticed that
those tutorials were somewhat out of date as now there are the Window
and ActionBar advisor classes. I've looked for some similar change in
3.1 for this problem, but I cannot locate it. I was using 3.1.1, but I
downloaded 3.1.2 today and still get the same results.
If anyone can point me in the right direction, that would be great.
Basically, all I want is an RCP app where I have 1 perspective and 1
view. The view will be a simple form with a canvas and a properties
window. I know I can just make an SWT app doing this most likely, but
I was trying to give RCP a whirl :-)
Thanks,
Dan

Dan,
add you perspective id in
your WorkbenchWindowAdvisor#getInitialWindowPerspectiveId

I don't see getInitialWindowPerspectiveId in WorkbenchWindowAdvisor's
class definition, but I know that I have this in my WorkbenchAdvisor
subclass. I reference my perspective's ID there just as it is written
in the plugin.xml file. That function does get called, that is one of
my break points.
However, my perspective is still never created as far as I can tell. My
experience with the tutorial's code is that it's perspective is also not
created, but when you run the application, it does show the view. There
is very little difference between it and my own code, hence my confusion.
Thanks,
Dan

deleted it and now it works as expected.

There must be some way to circumvent this, unless it's a bug. In the
Addison-Wesley Eclipse Series book "Eclipse Rich Client Platform" by
McAffer/Lemieux, on page 63, it _explicitly_ tells you to override the
initialize() method in the ApplicationWorkbenchAdvisor class, and to
put
configurer.setSaveAndRestore(true);
in the method. This is the first actual source code change the book
asks you to make after running the Hello RCP wizard, so the following
described behavior is very easy to reproduce.
When I do this (I'm using Eclipse 3.2) it _does_ enable the saving and
restoring of the window size and position, but it also disables the
createInitialLayout() method of the perspective, and my perspective is
not executed. I have a System.out.println() at the start of the
createInitialLayout() method which does not get written to the
console, whereas it did before I overrode the
ApplicationWorkbenchAdvisor initialize() method.
If I comment out the overridden initialize() method again, the
perspective is executed, so I see the sop() in the console, but it no
longer saves my window size and position.

When you first create a perspective is the only time that
createInitialLayout(*) is run (or a reset perspective).
So if you have activated save and restore and you restart your app, your
perspective should be restored from the workbench settings. It's not
creating a new perspective, just restoring your current one.
But your perspective should have been called once, at some point.

This is the expected behavior. If your createInitialLayout method were
called, it would wipe out the saved state of the perspective.
If you have setSaveAndRestore true and you make code changes in your
createInitialLayout() method, you have to clear out your workspace upon
launching. In the launch config, check the Clear workspace before
launching on the Main tab. If you leave the Ask for confirmation before
clearing checked, you will be asked whether you want to clear on each
launch.
