back button results in a blank
Hi there,
I notice that many times when I click the browser's back button, when I
expect to see the form previously that was displayed, instead I get a
blank page and have to click the browser's refresh button to retrieve
what was there.
This is IE8 in particular.
Is there any simple way to preserve what was there before so that on
clicking the back button it displays directly instead of having to click
refresh on a blank page?

I like problems which resolve themselves ;-)
Thx for the update,

sorry about this, but it is indeed my error.
The back button works with Cocoon flowscript even in IE.
The problem was I was catching an error and displaying the error to the user in a new page that replaced the old one.
I gather in this process, the "continuation" gets "lost" and as a result, the back button no longer works.
What I was doing was as below:
if(errorMsg.length()>0) {
errorPage("There appear to have been important changes made already. Are you sure you want to clear all the fields before saving this task? If yes, please click the back button. Otherwice, click Create to start a new entry.")
return;
}

Yes, sorry about that I am indeed using Flowscript (Cocoon 2.11).
I did read that "back button" issues are confined to IE and FF but not to Chrome. I have not confirmed that.
I should do my homework and install the full Flowscript example set that comes with Cocoon and try it with those.

I am assuming Paul is using flowscript (continuations) and they 'should' solve the back button problem for all I know. But let's first find out which version of cocoon he's using and if he is indeed using flowscript.
@Paul,
Could you perhaps setup a minimalistic test case and share it so we can test ourselves?

Hi Paul,
The browser's back button problem is not a specific cocoon one.
I believe that it could have different causes.
It is even browser specific, I believe. The back button is just supposed to show the "previous viewed resource".
I usually stick to 'restful design principles'. This may help to alleviate back button issues.
As a principle, I never make webapps block the back button.
I know this sounds a bit vague, but it's for the moment my best shot. Anyone else?
Kind regards,
Jos
