XText editor embedded in Properties View [message #1407415]

Hi,
I have got my XText grammer working nicely within a Papyrus editor by following the existing OCL embedded editor code, see http://git.eclipse.org/c/papyrus/org.eclipse.papyrus.git/tree/plugins/uml/textedit/org.eclipse.papyrus.uml.textedit.constraintwithessentialocl.xtext

Now I want to get my grammer embedded in a properties view. I have created an extension for my langauge using org.eclipse.papyrus.uml.properties.languageEditor but I get stuck when implementing an editor that implements the interface org.eclipse.papyrus.uml.properties.widgets.BodyEditor Is there an example I can follow somewhere? Right now I get an NPE when I try and use the properties view, as expected Smile

Hi

Let me know when you have solution; embedding OCL in the UML properties
page has been on my to-do list for a few years.

Papyrus does have the OCL editor embedded into the Properties view for OpaqueExpressions doesn't it? See screenshot. This is the kind of integration i'd like to reproduce for my language.

Yes. It's nice, but for the UML Model editor I need support in the old
style Properties View.

Hi Ronan,

Did you have a look at org.eclipse.papyrus.uml.properties.xtext.XtextLanguageEditor, which is the Body editor registered for OCL expressions? It seems generic enough to handle any XText grammar

Regards,
Camille

Aha. Ok I just set the org.eclipse.papyrus.uml.properties.languageEditor extension point property to editor="org.eclipse.papyrus.uml.properties.xtext.XtextLanguageEditor" and it works!

<extension
point="org.eclipse.papyrus.uml.properties.languageEditor">
<editor
editor="org.eclipse.papyrus.uml.properties.xtext.XtextLanguageEditor"
language="MyLang">
</editor>
</extension>

Thanks Camille.

Ps There seems to be issues related to priority/default editors, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=441962
