Scheduler - Frozen rows are not processed in onRowFilter

let resource = {
	id: DayPilot.guid(),
	name: '',
	frozen: 'top'
};

this.addEvent(resource, {id: DayPilot.guid(), text: 'test'})

this.personResources.push(resource);

Frozen rows are now supported by the row filter in the latest sandbox build (2023.1.5544).

The documentation is updated as well:
https://doc.daypilot.org/scheduler/frozen-rows/

> I also have a problem when I want to show the top frozen row the first time I add an event to it. In this case the frozen row remains hidden.

It's not clear how you update the resources - it's necessary to call update() after changing the "resources" array:

dp.resources.push({id: 1, name: "Row 1"});
dp.update();

Or you can add an up-to-date resources array to "options" object of the update() method:

const resources = getCurrentResources();
dp.update({resources});

You can also add a new resource to the bottom using rows.add():

Or as the last child of another resource using rows.addChild():
