Unable to use View field source in a component nested in a component with error message array_keys(): Argument #1 ($array) must be of type array, null given

zigazou → changed the visibility of the branch 3506138-unable-to-use to hidden.

The proposed patch works for my case but I’m really not sure if this is what needs to be done.

Thanks so much. Can you do a MR?

MR has been done.

Hi @zigazou!
Thank you for your contribution.

I confirm that this fix resolves the issue with the “View field” in the nested component within Views.
It seems that when we use nested components, the View’s query may not have been executed at that point, resulting in an empty $view in $this. Calling $view->build(); fixes this by rebuilding the View and fetching the data successfully.

However, I’m not entirely sure about the performance impact of this approach. Perhaps we could add a workaround to check the state of the View and apply this fix only when necessary.

I added screenshots with the View state without the fix and with it.

Thanks so much @smovs

However, I’m not entirely sure about the performance impact of this approach.

Hi Christian, can you check this?

The first lines of the build method are the following:

    if (!empty($this->built)) {
      return;
    }

Therefore calling the build method on an already built view should not have a performance impact.

On another side, this might hide an incorrect view manipulation along the process.
