Hi All,
I need an help please.

I have an application with an Application.e4xmi which contains something like the file attached. I've a plugin where I contribute via fragment.e4xmi (attached) by adding a perspective.

The prespective is perfectly showed and it works but it is not persisted properly. If open a couple of view after the restart of my application are not showed!

I think the mistake is in the model as the plugin is (looks like) properly filled out ...

what mistake do I make?

thanks in advance.

Kasper.

So what's the value in the plugin.xml file where you contribute the
fragment - wild guess is that this one is merged in every time and
replaces the current perspective.

Hi Thomas,
thanks for your reply! really appreciated.

   <extension
         point="org.eclipse.ui.perspectives">
      <perspective
            class="com.TEST.ui.perspective.App"
            fixed="false"
            icon="icons/app.png"
            id="com.TEST.ui.perspective.App"
            name="App">
      </perspective>
   </extension>

and

   <extension
         id="APP"
         point="org.eclipse.e4.workbench.model">
      <fragment
            apply="always"
            uri="fragment.e4xmi">
      </fragment>
   </extension>

But basically the thing is:
I have an Application.e4xmi with one empty "PerspectiveStack" with ID: com.TEST.perspectivestack.0
I have a fragment.e4xmi with a Model Fragment with ID com.TEST.perspectivestack.0 ... here I want to contribute to the (Application.e4xmi) model

what I see is the correct perspective but not persisted ...

your fragment is merged *always* which means on each start the persisted
state is overridden by the fragment who defines the initial setup.

You need to set the value to never or notexist.

can confirm that I have to set the (PerspectiveStack) ID from the application.e4xmi and the one into the fragment.e4xmi (ModelFragment) as the same? I mean having the PerspectiveStack in the application.e4xmi with the same id (ModelFragment) into the fragment.e4xmi

BTW, by having this configuration still not working:
/// Fragment.e4xmi:
<fragments xsi:type="fragment:StringModelFragment" xmi:id="_jeCj0FRvEeSzRrIrWuanPw" featurename="children" parentElementId="PerspectiveStack">
<elements xsi:type="advanced:Perspective" xmi:id="_xoLHQFRvEeSzRrIrWuanPw" elementId="com....." label="App" iconURI="">

///Application.e4xmi:
<children xsi:type="advanced:PerspectiveStack" xmi:id="_j4rA4HQCEeWYc45L5sV2Pw" elementId="PerspectiveStack"/>

/// plugin.xml of the fragment plugin:
apply set to "notexist"

/// plugin.xml of the Application.e4xmi:
apply set to "notexist"

the only strange think is that I've removed from the Application.e4xmi the PerspectiveStack and having one into the Fragment.e4xmi with the ID: com.MY_ID.etc ....
it works! but if I put the ID: org.eclipse.ui.ide.perspectivestack ... it doesn't work.
why this?
