Add check in app

[michielbdejong]

Seeing if I can move the Workflow Engine check into the MFA Zones app to reduce the need for changes in Nextcloud Server itself.

backend seems to work, now looking at frontend.
As per nextcloud/server#40235 (comment) maybe we can call window.OCA.WorkflowEngine.registerCheck.
Will try to copy how https://github.com/nextcloud/flow_webhooks/blob/d06203fa3cc6a5dc83b6f08ab7dd82d61585d334/src/main.js#L27 does it!

this.$store.getters.getChecksForEntity(this.rule.entity) is still failing. Should debug in the web console

It seems I'm getting close - my JS code is being compiled with Vue and executed on page load. The problem I have now is:

Object.keys(window.OCA)
Array(10) [ "Search", "Files", "Sharing", "Trashbin", "Circles", "SystemTags", "Comments", "Viewer", "Text", "Theming" ]

So WorkflowEngine is missing from that list, despite the fact that it's being set in /var/www/html/dist/workflowengine-workflowengine.js

[michielbdejong]

Ah! It doesn't always get set.

When on http://sunet-nc2/index.php/settings/admin/workflow the list is different:

Object.keys(window.OCA)
Array(10) [ "Search", "WorkflowEngine", "Theming" ]

But there our mfazones code is not loaded! That is only loaded in the main files view. Will dig deeper on how NC decides which app-specific JS scripts to run on which page.

Ah I think I found the answer on https://docs.nextcloud.com/server/28/developer_manual/digging_deeper/flow.html

In the RegisterOperationsEvent listener we need to registere the above JS bundle.

I can get it to call our Application::register function from https://github.com/nextcloud/server/blob/dc2066bc26d9d92ddceaf15f9be447a5dbffb8ca/lib/private/AppFramework/Bootstrap/Coordinator.php#L142 now, I'm pretty confident now that I can get mfazones working without patches to nextcloud/server.
