> IMHO the sync of IJSONModel with editor is the most important and should be done/fixed before fixing, improving other features. But it is the most hard too.
> At first, we should validate the IJSONModel API
> The big problem with JSON Editor is that the IJSONModel, IJSONPair, IJSONDocument, etc. There are a lot of copy/paste from XML/CSS plugins so this model and the implementation should be really fixed/improved.
> For instance completion works when editor is opened, but it is broken after some changes of the text editor. It is because IJSONModel is not very well sync.
> The most bugs that I see like:
>  * https://bugs.eclipse.org/bugs/show_bug.cgi?id=486606
>  * https://bugs.eclipse.org/bugs/show_bug.cgi?id=485694
>  * https://bugs.eclipse.org/bugs/show_bug.cgi?id=486849
>  * https://bugs.eclipse.org/bugs/show_bug.cgi?id=486524
> are linked to this sync problem.
> So tests https://github.com/angelozerr/eclipse-wtp-json/blob/master/core/org.eclipse.wst.json.core.tests/src/org/eclipse/wst/json/core/document/JSONObjectDocumentChangesTest.java must be completed when sync of model is improved.
> I will try to create a patch for adding tests https://bugs.eclipse.org/bugs/show_bug.cgi?id=486238 
> It's a very hard task, so good luck to do that.
