Re: Easier way to accomplish setResponsePage(Class, PageParameters)

[Ryan O'Hara]

Argh.  I just tested the this.getPage(), and although it worked at  
some point, it doesn't work now - I apologize.  We need portable  
URLs, but we were looking for a method requiring less maintenance.   
Thanks, again for the response.

how would setPage(this.getPage()) then work???
If you want those kind of urls with state in the urls you have to  
create a
PageParameter object
you can reuse existing or tweak an existing or create a new one

Or do you just want nice urls that dont have to work when there is no
session?
use Hybridurlencoder to mound the page then you can do setPage()

Thank for the response, Johan.  I don't think this is what we're  
looking
for, however.  If the user changes a form parameter, it will not be
reflected in the old page parameters.  Any other ideas?

Thanks,
Ryan

 call super(parameters) in the page constructor
then getPage().getParameters() should have the parameter map

 We are trying to figure out the best way to make our URLs portable.
 Currently, we mount a QueryStringUrlEncodingStrategy in our  
application
class.  Then, in the beginning of the page's constructor, page  
parameters
are mapped to instance variables.  Then, when the form button is  
clicked,
a
map of parameters is created to pass to setResponsePage(Class,
PageParameters).  It seems like mapping the parameters to  
variables and
creating a map of parameters to setResponsePage() can be avoided  
by using
setResponsePage(this.getPage()), but the URL produced is not  
portable.
 Having to map parameters to instance variables and maintain a  
map to
pass
in is high maintenance.  Is there a better way to do this?   
Thanks for
the
help.
