Code Action Resource access [message #1869756]

Hello,

I have an implementation which exploits the xtext ICodeActionService2 implementation. From the Options (org.eclipse.xtext.ide.server.codeActions.ICodeActionService2.Options) I should be able to access both document and resource and allow querying the model to determine if an executeable command should be applicable:

```
val offset = document.getOffSet(position)
val element = resource.resolveContainedElementAt(offset)
```
pre 2.20 the codeActions Options were populate with the resource - e.g.:

https://github.com/eclipse/xtext/blob/fedf312fcc8f88605fdf182e3ae2041de793ce4a/org.eclipse.xtext.ide/src/org/eclipse/xtext/ide/server/LanguageServerImpl.java#L785

but now this is the not the case:

https://github.com/eclipse/xtext/blob/main/org.eclipse.xtext.ide/src/org/eclipse/xtext/ide/server/LanguageServerImpl.java#L818-L823

so the resource is always null.

I was wondering if there was a way to access the resource from somewhere else in the IDE module - I have available a ProjectManager via the ServerModule, but not entirely sure how to initialise this properly

many thanks for any help

Maybe you can do some archeology on
https://github.com/eclipse/xtext/commit/955533e89e829c3ca0e182a4e47eec3db5727bcc#diff-de69d0b3cc6ee48a1c1dd195a62c2109a69addda2bc3d5729fd58889bf6344e3

https://github.com/eclipse/xtext-core/pull/1915

And why the set resource is not called.

Thanks a lot for the links here - the correct way now to do this (for reference in case someone else find this) is to use e.g.

```
options.languageServerAccess.doSyncRead(options.URI, [ Context context |
val resource = context.resource
val document = context.document
....
)
```
