> I often use {{#initModel}} in my pages because I find it very convenient in many usecase...
> Actually there is an issue in a certain scenario: let's say #initModel is supposed to return a {{CompoundPropertyModel}}. So I am free to explicitly *not* provide the model to the component that consume this model, a label for instance. But, If the page only contains those 'compound' components, #initModel is never called so the model is never set.
> A workaround is to set the model manually:
> {{this.setModel(this.initModel());}}

> this topic was discussed before:
> When searching parental components for a IComponentInheritedModel, #initModel() is skipped to prevent unnecessary creation of intermediate models. See the comment on line 3788 ff:
