Hi,
I want to contribute a complete perspective including the views from a
fragment.e4xmi to the application model.
Inside the Application.e4.xmi I have defined:

<children xsi:type="basic:TrimmedWindow"
xmi:id="_XwsN6gMWEeKkEbp87BcYwQ" label="Application" width="500"
height="400">
<children xsi:type="advanced:PerspectiveStack"
xmi:id="_XwsN8gMWEeKkEbp87BcYwQ" elementId="de.ww.perspectivestack"
selectedElement="_XwsN8wMWEeKkEbp87BcYwQ">
<children xsi:type="advanced:Perspective"
xmi:id="_XwsN8wMWEeKkEbp87BcYwQ" elementId="de.ww.core.perspective"
label="Perspective">
<children .........

At my fragment.e4xmi I have defined the following Model Fragment:

<fragments xsi:type="fragment:StringModelFragment"
xmi:id="_kAkdUAPVEeKUqvnYpyiNPg" featurename="children"
parentElementId="de.ww.perspectivestack">
<elements xsi:type="advanced:Perspective"
xmi:id="_pZ4EUAPVEeKUqvnYpyiNPg" elementId="de.ww.docmgmt.perspective"
label="DocMgmt">
<children xsi:type="basic:PartSashContainer"
xmi:id="_BVhKoAPBEeKUqvnYpyiNPg"
elementId="de.ww.docmgmt.partsashcontainer.main" horizontal="true">
....
....
....
</children>
</elements>
</fragments>

I also add some more model fragments with handlers and commands.
So I add a Handler to switch to the defined perspective with the
following code:

@Execute
public void execute(MApplication app, EModelService modelService,
EPartService partService) {
MPerspective element =
(MPerspective) modelService.find("de.ww.docmgmt.perspective", app);
partService.switchPerspective(element);
}

But this method doesn't find the defined perspective and the
modelservice returns a null.

What have I do wrong???

Thanks in advance

Heiko

Hi Heiko

your Handler-code looks good to me. I am doing the same thing, so it should work.

To test what your model looks like after start of the application, you can use the e4 live model editor.
1) You need to add some bundles to your product:
- org.eclipse.e4.tools.emf.liveeditor
- org.eclipse.e4.tools.emf.ui
- org.eclipse.e4.tools.emf.ui.script.js
and the required plug-ins
2) After you start the product like this, press Alt-Shift-F9

Now you can inspect your model and check, if all the elements are there and if the IDs are all correct.

Hope this helps!
Christoph

Hi Christoph,

thanks for the tip, I have read about it but now used until now - it's a
nice feature. :)
It helps me to see that my defined perspective are not available at the
model.

And it helps to start an app with the option "clear workspace" sometime. :)

Now it works.

Greetings
