Can I open a Xtext editor for a element tree contained in another model? [message #837555]

Thu, 05 April 2012 16:37

Hi,

I have a ecore model that has the following structure:

RootContainer
- ContainedTreeOne
-- ContainedElement1
-- ContainedElement2

- ContainedTreeTwo
-- ContainedElement3
-- ContainedElement4

Currently the model is being visualized using a SWT treeviewer and edited in a SWT form editor that is opened when the element is double clicked.

I would like to add another child in RootContainer, let's call it ContainedTreeTwo. This submodel is like the EntityModel example, so I would like to edit it using a Xtext editor that should be opened by double clicking the item in the view.

could I do such thing ?

If yes, could someone point me to some path ?

regards,

Cristiano

Now I did, thanks.

Summaring, It seems that I need to use an EmbeddedEditorFactory and a IEditedResourceProvider implementation, right ?

But I couldn't get there step yet because I couldn't create the Xtext project based on my ecore project. I'm getting this error after select the ecore package, the node and the project starts to be created:

Any hint about what could be generating this error?

Hi,

No I have no idea, can you share a minimal reproducable ecore +
genmodel

I think I've discovered the motive of the error.
In my ecore I was using the registered package from http://www.eclipse.org/xtext/common/JavaVMTypes (I've use the runtime version). So, I had something like this:

<eClassifiers xsi:type="ecore:EClass" name="Feature" abstract="true">
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
    <eStructuralFeatures xsi:type="ecore:EReference" name="type" eType="ecore:EClass http://www.eclipse.org/xtext/common/JavaVMTypes#//JvmTypeReference"
        containment="true"/>

change to this makes the project to be created:

  <eClassifiers xsi:type="ecore:EClass" name="Feature" abstract="true">
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
    <eStructuralFeatures xsi:type="ecore:EReference" name="type" eType="ecore:EClass platform:/plugin/org.eclipse.xtext.common.types/model/JavaVMTypes.ecore#//JvmTypeReference"
        containment="true"/>
  </eClassifiers>

But when I try to run the .mwe2 file I got this error:

2133 [main] ERROR ipse.xtext.generator.LanguageConfig  - [XtextLinkingDiagnostic: null:8 

Couldn't resolve reference to EPackage 'platform:/plugin/org.eclipse.xtext.common.types/model/JavaVMTypes.ecore'.]

I've tried to add this to the mwe2 file :

		registerGenModelFile = "platform:/plugin/org.eclipse.xtext.common.types/model/JavaVMTypes.genmodel"

But this not work. Could you point me to the right way of doing such importing?

thanks

Cristiano

It should work with the nsURI if you add a registerGeneratedEPacke
(or something like that) with the full qualified name of the package

Sorry, couldn't follow you. What do you mean with "with the full qualified name of the package"? could you give more detail on that?

btw, I've tried this and seems to be working (at least do not throw errors):

	bean = StandaloneSetup {
		scanClassPath  = true
		registerGeneratedEPackage = "org.eclipse.xtext.xbase.XbasePackage"
		registerGenModelFile = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
		registerGenModelFile = "platform:/resource/org.eclipse.xtext.common.types/model/JavaVMTypes.genmodel"
	}

Hi Christian,

Come back to zero again. I've created a new ecore project based on the .ecore generated by Domain example.

I've modified the imports on it to platform:/plugin/org.eclipse.xtext.common.types/model/JavaVMTypes.ecore as I did before with the other project. but I can't run the xtext wizard with it. Sad

Ok, I will...

But just to know, have you been able to reproduce it in your environment ?

Hi,

Humm... bit strange :/

The version that I was using is Xtext SDK 2.3.0.v201204031826 with Juno M6 in a MacOS.

I've update to version 2.3.0.v201204050926, but still getting the same error in the attached project.

I've opened the ticket here: https://bugs.eclipse.org/bugs/show_bug.cgi?id=376362

As I have one goal to accomplish, that is to open an xtext editor with one nodetree in my model, I've tried Xtext SDK version 2.2.1.v201112130541 with Indigo.

Sorry to say, unfortunately I got the same error. Sad

I'll remove the links to other packages just to try to resolve the open editor thing...

thanks

Hi,

A similar need where I need to partially edit a model as part of the tree. Used EmbeddedXtextEditor to open a partial element of the model for editing. This has been achieved as embeddedEditor.createPartialEditor("", editableText, "", true), where editable text is the partial part of the model. But my content assist & other handlers are not working correctly or as required.

I am not using text editor classes as my base class for editor class & have used form page. Let me know if I have gone down the wrong path or something else would be needed to go ahead.

Not sure whether editableText is the correct way for being the partial model as in Xtext 1.0 while integrating with GMF we used to attach with rule rather than string?

Regards
Vishal
