[ovirt-devel] 回复： In windows OS & firefox brower, Window.Location.replace(url) would stop System to execute Command, and would not catch any error info.But other OS like firefox in linux would not happen like that

Hi Alexander
    I tried your method ,and it works! right, I want to redirect another page after user logged out, but also I want Ovirt-engine could execute Logout user command to clear session.
    I tried to insert Window.Location.replrace in LoginModel.java , ApplicationPlaceManager.java etc.  In any version firefox of window7 OS,  even if another page could be redirected correctly ,ovirt-engine would not execute Logout user command ,so user's session would  not be clear, and I can see previous  page. 
    It's strange that this stuff would not happen in other browsers(chrome/IE), even the firefox of Linux.  I try to replace in callback() as your advice, now, for every browsers, ovirt-engine can execute logout command, it works! Thank you so much for your patience ：)

Hi,

I am trying to decipher your message (it got garbled for some reason). And I 
am trying to understand what you are trying to do. If I understand correctly 
you want to redirect to some other page after you have logged out of the web 
admin.

To get back to the specifics of your question. The DefaultPlace is the #XXX in 
the URL you are sent to (note its not an actual redirect, since there is no 
round trip to the server), if you don't specify a particular place. When you 
do #vms the whole DefaultPlace mechanism is not in play since you specified a 
particular place.

What does happen is that the framework asks the LoggedInGatekeeper if the user 
is logged in (in the canReveal() method). If the user is logged in, it will 
proceed to the normal place requested (in your example #vms). If the user is 
not logged in, it will switch places to #login and display the login screen.

Now you say you are using 3.4.5 which is quite old, and its been some time 
since I worked with it. If I understand correctly what you are trying to do, 
don't mess around with the DefaultPlace. In BaseApplicationInit there should 
be a 'onLogout' method. In there should be a callback that happens AFTER the 
user is logged out from the server. Right now it says something 
Window.Location.reload() to reload the page after the logout. You should be 
able to put your Window.Location.replace in there (replace the reload with the 
replace). Which I think will do what you want.

If it doesn't do what you want, I am going to need some more information on 
what it is that you are trying to do.

Alexander
