tasklist not opening editor (no binding for EditorContextService)

[metadatadriven]

Hoping someone can help or at least point me in the right direction!..

I'm trying to get the gslp-example node-json-theia running in my theia project

• theia v1.61.0
• @eclipse-glsp/theia-integration 2.4.0-theia1.60.0

I have basically copied the following glsp-example folders into my project repo (and set/edited package.json etc.)

• tasklist-theia
• tasklist-glsp-client
• tasklist-glsp-server

Everything builds ok and Theia runs ok. The glsp log looks ok:

6:09:38 PM info -  [SocketServerLauncher] The GLSP server is ready to accept new client requests on port: 36523 
6:09:56 PM info -  [SocketServerLauncher] Starting GLSP server connection 
6:09:56 PM info -  [DefaultGLSPServer] Initializing server with: applicationId: 45f14fbc-3e71-400c-b62b-00dd8bb48c80, protocolVersion: 1.0.0 

However, when I click on the example.tasklist file in the workspace, the editor does not open and I get the following error in the Javascript/Developer tools console:

Uncaught (in promise) Error: No matching bindings found for serviceIdentifier: EditorContextService
    at _validateActiveBindingCount (planner.ts:170:15)

    at GLSPDiagramWidget.configure (glsp-diagram-widget.ts:112:82)
    at Object.create (diagram-widget-factory.ts:47:27)

I'm going round in circles!.. any help or ideas appreciated.
Thanks

PS. The glsp-example tasklist runs ok on my machine out the box (i.e. from a new clone repo)

So, trawling through the startup console log, I found the following warning:

2025-05-27T13:33:52.844Z root WARN Couldn't restore widget for tasklist-diagram-diagram-manager. Error: Error: No matching bindings found for serviceIdentifier: EditorContextService

Is the "double tasklist" an issue in tasklist-diagram-diagram-manager?

[tortmayr]

Hi @metadatadriven,
I don't think that the "double tasklist" is the issue here. This is just how the id of the manager is derived by default:

export function deriveDiagramManagerId(diagramType: string): string {
    return diagramType + '-diagram-manager';
}

In your case everything is building correctly, but then during runtime you get an inversify error.
This could be an indicator for wrongly resolved inversify dependecies. The injection approach of inversify only works correctly if
EXACTLY ONE version of inversify is used in the entire package.

Please check if that is the case. (You can use yarn why inversify or the npm equivalent for that).
If you have multiple versions you could try to:

• remove your lock file and build from scratch.
• If that does not work you might have to enforce a specific version via resolutions (yarn) or overrides (npm)

[metadatadriven]

Thanks for your suggestion @tortmayr - I did have a "hello-world" extension in the project that had inversify as a dependency in the extension package.json - I have removed the extension from the project completely, also added a yarn resolution for inverify to 6.1.3.

I have deleted node_modules and yarn.lock and re-installed and re-built everything.

Unfortunately I am still getting the same runtime error.

My yarn why inversify is:

$ yarn why inversify
yarn why v1.22.22

I'm assuming that the EditorContextService is not being bound correctly but cannot track down where/why this might be?

[tortmayr]

The EditorContextService is a core service that is bound in the default module of GLSP. If inversify cannot resolve it, that's typically an indicator that something is wrong with the overall setup.

I'm trying to get the gslp-example node-json-theia running in my theia project

theia v1.61.0
@eclipse-glsp/theia-integration 2.4.0-theia1.60.0
I have basically copied the following glsp-example folders into my project repo (and set/edited package.json etc.)

tasklist-theia
tasklist-glsp-client
tasklist-glsp-server

Did you also upgrade the other GLSP dependencies to 2.4.0?
(@eclipse-glsp/client and @eclipse-glsp/server)

[metadatadriven]

Bingo! The @eclipse-glsp/client and @eclipse-glsp/server dependencies were still at 2.3.0 - once I changed them to 2.4.0 then all working as expected!!

Really appreciate your help,
Thanks!

updating to GLSP 2.40 solved my issues too
