-----------------------------------------

             Summary: initModel and 'compound' components only
                 Key: WICKET-5792
                 URL: https://issues.apache.org/jira/browse/WICKET-5792
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 7.0.0-M4, 6.18.0
            Reporter: Sebastien Briquet
            Priority: Minor


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:
