Hi,

having migrated my RCP from eclipse 3.0 to 3.1, my intro is shown now on
every startup. Is there any 'switch' to stop this behaviour?

Thanks,

Dirk

It probably depends on your workbench advisor that you've written for the RCP (and indeed, assuming you've got one :-)

Have a look at the openIntro() method of WorkbenchWindowAdvisor:

http://help.eclipse.org/help31/topic/org.eclipse.platform.do c.isv/reference/api/org/eclipse/ui/application/WorkbenchWind owAdvisor.html#openIntro()

"The default implementation opens the intro in the first window provided if the preference IWorkbenchPreferences.SHOW_INTRO is true. If an intro is shown then this preference will be set to false. Subsequently, and intro will be shown only if WorkbenchConfigurer.getSaveAndRestore() returns true and the introduction was visible on last shutdown. Subclasses may override."

This changed from 3.0 to 3.1 (before, it was elsewhere http://help.eclipse.org/help31/topic/org.eclipse.platform.do c.isv/reference/api/org/eclipse/ui/application/WorkbenchAdvi sor.html#openIntro(org.eclipse.ui.application.IWorkbenchWindowConfigurer)

You should be able to continue to use the old mechanism, but only if you've got the compatibility plugin loaded. If you're looking at supporting 3.1+, then switch to using the new method.

If you're already doing this, check what the preference for the IWorkbenchPreferences.SHOW_INTRO is being set to, and if it's being saved appropriately. (It could be that you're debugging and cleaning the workspace each time, for example ...)

Thanks for the tip Alex.

I also had the same problem with Eclipse, and I know from other developers
that they are getting the same problem.

Even more, if you create a sample RCP application from the wizards, and
declare the default intro page (org.eclipse.platform), and export it using
the product export wizard, then you'll see that the intro page always
appear! And is a project very, very simple.

Now, I took a look and examined the code of the openIntro method and it
seems that the error is that Eclipse is not able to save the API prefs in
the PrefUtils.saveAPIPrefs() call. There is no other possibility.

To fix this, I created my own check mechanism with my own preferences
file, and all worked fine. But the bug is there yet.

Regards,

Martin

Hi Martin

Its exactly the same problem in my RCP. Did you write a bug report?

Regards,

Dirk

No.

First, I thought that it could be my mistake, but after seeing some forum
posts, it seems that there is a lot of people who are getting the same
mistake.

Hi Martin,

I reported a new bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=107698

Let's wait and see if it will be affirmed by the eclipse developers.

Regards,

Dirk

yes. I encountered the same problem.

While can't wait for a fix, I worked out a workaround for the issue. The
main steps are:
1. remember whether there is intro view when the RCP exits
2. next time the RCp starts, check the remembered info, and if no intro
view, then alrways close the into view immediately
3. otherwise, just put the into view into the standby mode.

Note: you alwyas want to let the intro view be put into the standby mode
first even if it needs to be close because otherwise those other fast
view such as search help etc will have the exact problem as the intro view.

Thanks.
Bing.

Hi.

You don't need to close the intro view manually. You can override the
openIntro() method in your window workbench advisor, and if the intro view
didn't exists, then you do not call super.openIntro() method, otherwise
you continue with your process.

Regards.
