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

whats the usecase for component replacing itself during oninitialize()? it doesnt seem valid to me...

> When calling this.replaceWith within the onInitialize method, wicket throws an exception:
> "Last cause: org.apache.wicket.Component has not been properly initialized. Something in the hierarchy of com.mycompany.PanelA has not called super.onInitialize() in the override of onInitialize() method"
>   
> This happens because detach is called on the panel being replaced which clears Component.request flags (sets to 0) which causes the exception on line 864 of Component.java:
> if (!getRequestFlag(RFLAG_INITIALIZE_SUPER_CALL_VERIFIED)) {
>             // throws here
> }
