Panel switching and back button

[Cristi Manole <cr...@gmail.com>]

Hello,

I am implementing navigation through my application by switching panels.

When the user presses the back button, I'd like to show the previously
displayed panel. Is this possible?

Thanks,
Cristi Manole

Hmhhh... isn't there a Javascript function which allows to replace the URL
of the current page in the history? I'm not sure this would work, but
couldn't you try this:

1) replace the panel
2) reload the IFrame
3) now manipulate the browser history to point to the currect URL for the
current page version

Re: Panel switching and back button

[Martin Grigorov <mc...@e-card.bg>]

We use ReallySimpleHistory
(http://code.google.com/p/reallysimplehistory/) for this. Every AjaxLink
(or component+AjaxEventBehavior) records the url of the current page +
some indicator in the hash path (e.g. '../blah/page#someId') in rsh.js
(via AjaxCallDecorator).

Later when the user presses 'back button' the request is to the same
page with the id in the hash. Then 'onload' JS function checks the
location.hash and if it is nonEmpty it makes something like this:

Wicket.$('someId').click()

and this actually calls the behavior which will set the page's state
back to the previous one.

this works only for ajax "navigation". The models behind are always the
latest version.
If you need the previous version of the models then you need to create a
new version of the page on every Ajax request too. But this is getting
complex.

yes, I know, I'm trying to figure out a solution myself.

I was sure though somebody else ran into this. :)

Aha, the problem is that ajax does not cause a history entry to be created.
I've seen workarounds for this (not with wicket, though) which reload a
hidden IFrame each time they make a relevant change. I can't see right now
how that helps you in wicket, tough.

I would expect that to happen by default. Replacing a panel should create a
new page version which should change the Page URL. Are you using AJAX?
