completionProviders not working

[f4n0]

Hi,
With the latest AL Language Version (Version: 18.0.2293710) the Code completionProviders are not showing.

there is also an error from the extension host, don't know if it is related or not:

Same for me.
For example: If I type SalesLi I expect SalesLine: Record "Sales Line" to automatically show up, but that isn't the case anymore.
Now I must manually hit CTRL+Space to show the completion suggestion, but it doesn't trigger (like I said) automatically anymore for me.

I've released a new version last week, the problem should be fixed.

Hey @anzwdev

Unfortunately, it’s still happening (at least for me) and I managed to find out why:

AZ/AL autocompletion seems to conflict with Copilot’s inline suggestions. I disabled all extensions and then re-enabled them one by one. After disabling AI Features by right-clicking the GitHub Copilot Chat extension and selecting "Disable AI Features", the inline code suggestion no longer appeared and the AZ/AL completion suggestion showed up instead.

Sadly, I don’t know why this has started happening now, since Copilot inline suggestions have been around for a long time and seemed to work properly along with AZ/AL completion suggestions.

Can you reproduce this behavior and confirm my assumption (or anybody else? 😕)

Edit:

Edit 2:

My Copilot User settings:

"github.copilot.enable": {
        "*": true,
        "plaintext": true,
        "markdown": true,
        "scminput": false,
        "xml": true,
        "xlf": true,
        "yaml": true,
        "al": false
    },
"github.copilot.chat.codesearch.enabled": true,
"github.copilot.nextEditSuggestions.enabled": true,

@someC0d3r unfortunately, this is not my case. I've created a new profile, and installed only AZ AL (and the necessary dependencies), and made sure that Copilot is off, and it still doesn't work for me.
