Autocomplete shows multiple of the same item

[jtsom]

• VSCode Version: Code - Insiders 1.18.0-insider (dcee220, 2017-11-08T08:15:14.690Z)
• OS Version: Darwin x64 17.2.0
• Extensions: Extensions are disabled

---

Steps to Reproduce:

1. Start typing code. Autocomplete popup shows up.
2. Popup shows multiple items of the same thing - up to 8 to 10

Reproduces without extensions: Yes

A little more info... this seems to happen when VC Code is set to use it's own version of Typescript (2.6.1). When I switch to the version in the project (2.4.2), I see the correct popup items.

@jtsom If you scroll through these suggestions, do they all have identical descriptions?

TS 2.6 brought support for automatic imports. If there are multiple MatSnackBarConfig defined in your project, we will show an entry for each unique one. Selecting one should add the import from the corresponding file

[jtsom]

Yes, each one has the same description. It definitely looks like it's just duplicating the entries. Again when I switched to using the project's Typescript, the popup was much shorter.

Can you please collect the typescript server trace of this to help us investigate. To do this:

1. Set "typescript.tsserver.trace": "verbose" in vscode

2. Trigger the incorrect suggestion again

3. Open the output view and go to the TypeScript section

   

4. Share the output from there

Thanks

[jtsom]

Sure. Here you go. With a screenshot of what I did that generated the output:

FWIW, here's a screenshot with Typescript set to the project's (2.4.2):

Thanks for the additional info! I confirmed the bug and have opened microsoft/TypeScript#19922 to track this against TypeScript

Closing as upstream

Any idea when this is going to be filtered back to VS Code? I see the latest insiders has an insiders version of Typescript, but doesn't seem to fix the problem.

[mjbvz]

This should be fixed in TypeScript@next (Typescript 2.7). You can use this version in current versions of VS Code by following these instructions: https://code.visualstudio.com/Docs/languages/typescript#_using-newer-typescript-versions

[jtsom]

Sorry to say, this problem still exists with Typescript 2.7.

Here's screenshot from 2.6.2:

And here's one from the latest 2.7dev version - it's actually worse!
