Andrea Del Bene commented on WICKET-4112:
-----------------------------------------

IMHO we should consider to remove the following code

if (startComponent != null)
                {
                        path = startComponent.getId() + ":" + path;
                }




inside BaseWicketTester.getComponentFromLastRenderedPage(String path,final 
boolean wantVisibleInHierarchy). This method shouòd use an absolute path to 
retrieve component from page.
                
> WicketTester#startComponentInPage and WicketTester#assertModelValue have 
> inconsistent behavior.

> I try the following (in Pseudocode):
> tester = new WicketTester();
> tester.startComponentInPage(new Label("test","hello");
> tester.assertModelValue("test","hello"); --> throws
> java.lang.IllegalArgumentException: Component is not a container and so does 
> not contain the path test.
> Funny as it is, to make this work, you have to do the following assertion:
> tester.assertModelValue("", "hello");
> The error lies in
> public Component getComponentFromLastRenderedPage(String path,
>                 final boolean wantVisibleInHierarchy)
> in Line: path = startComponent.getId() + ":" + path; 
> I will provide a patch this evening.
