Hi,

i'm new to xtext and i've got a problem. i'd like to integrate xtext into my GMF-based editor. i've searched a lot an found a lot, but i still don't understand how to do it. i generated an GMF editor from a ecore-model. i've attached the ecore model. i'm not exactly sure if this is correct. but Root is the Model Object. Second is a node which can be placed in the GMF diagram editor. third is a node too.
now i want to define an attribute (expression) in Second, in which i can write a string with an Xtext editor which references the objects of Third. i created a new Xtext project from the existing ecore. but now i don't know how to combine the editors.
i found YAKUNDA but either it's hardly described, or i don't understand it. there also was some kind of example in xtext but it was removed.
can someone help me?

regards

gw

The example is still in Xtext's git repository. Look into the examples
folder. The Xtext documentation contains a link to it and explains the
basic steps.

In the meantime, Xtext ships with an EmbeddedEditor, that should make
things easier.

Still, to get it running requires decent knowledge on EMF, GMF and
Xtext. In the end you might only get a partially working solution not
covering each and every usecase. This - and the assumed death of the GMF
project in former Eclipse releases - made us skip shipping the example.

Not much docu so far. Get a grip on the UI injector
http://koehnlein.blogspot.com/2012/11/xtext-tip-how-do-i-get-guice-injector.html
and use the EmbeddedEditorFactory (with its builder pattern) to create
and configure the embedded editor.

The editor allows to only edit a partial model
EmbeddedEditor.createPartialEditor(String, String, String, boolean)
which is what I'd expect to be needed for labels in a GMF editor.

hi again,

i retraced the example and adapted my editor. now it nearly works. i can add an element. then the xtext popup show and i can write some text which is checked to be suitable to my grammar.
the problem is that when i write something and hit crtl+enter the popup closes but in the model-file only the new element was added but not the text i wrote for that element.
in console-view i get:

!ENTRY org.apache.log4j 4 0 2012-11-28 15:54:25.079
!MESSAGE org.eclipse.xtext.parser.impl.PartialParsingHelper - Invalid replace region [146 / length: 12] originalLength=26

can you help?

could it be, that there's a problem with my formatter, so he can't find the right position to insert the changes?
