View loaded event being called too soon?

[vjoao]

There is a plugin with this structure:

class Plugin extends AbsoluteLayout { }

and the constructView method does:

this.on(AbsoluteLayout.loadedEvent, (data: any) => {
    this.eachLayoutChild((view: View) => {

    .... some code with the children views   

    });

Because it's meant to be instantiated like that:

<PluginContainer>
    <SubView>
...
    </SubView>

    <SubView>
...
    </SubView>

    <SubView>
...
    </SubView>
</PluginContainer>

The problem is the eachLayoutChild is being called with no children whatsoever (looks like the onLoad event is being called before any child is constructed.

Is this the expected behavior? How to get the children list in this case?

Yes, at this moment the renderer creates parent views, attaches them to the visual tree (which fires their loaded events), and then proceeds with child views.

Since you are inheriting from a layout, perhaps it would be easiest if you override _registerLayoutChild and set up your children there:
