Bug in modal window.onBeforeRender <-> tests

[Martin Makundi]

Hi!

For some reason ModalWindow assumes request is not ajax even though it
is clicked via executeAjaxEvent:
                if (getWebRequest().isAjax() == false)
                {
                        shown = false; // This hides the button
                }

Thread [main] (Suspended (breakpoint at line 3191 in Component))        
        SettingsModalPanelContents$8$3$1(Component).setVisible(boolean) line: 
3191      
        ModalWindow.onBeforeRender() line: 820  
        ModalWindow(Component).internalBeforeRender() line: 1061

        NativeMethodAccessorImpl.invoke0(Method, Object, Object[]) line: not
available [native method]
        NativeMethodAccessorImpl.invoke(Object, Object[]) line: not available   
        DelegatingMethodAccessorImpl.invoke(Object, Object[]) line: not 
available       
        Method.invoke(Object, Object...) line: not available    

So the test fails with no good reason when the modal window assumes it
is not visible.

Basically what the test does is the following:
1. submit form
2. click links
3. executeajaxevent
4. submit form
5. executeajaxevent to open modal window
6. exceuteajaxevent on a button on the modal window <fails>

I found a workaround by placing "tester.setupRequestAndResponse()"
just before line 5. Ofcourse a true fix would we nice.
