prakashedl Pass Values from VF page A to VF page B without using query params
Hi All,
I am a newbie to salesforce. I would appreciate, if someone could help me with this. I have two visual force pages A and B. They both use common custom controller. VF page B should access the values set by VF page A. However, I do not want to pass values using apex:param, since I do not want the end user to see the values in query parameters. Is there any way I can access since both pages use the same custom controller?
VF Page A
------------
<apex:page controller="customcontroller">
<apex:commandButton action="{!gotoNextPage}" value="Next Page"/>
</apex:page>
VF Page B (/apex/pageB)
----------------------------
<apex:page controller="customcontroller">
Test Value :{!testValue}
</apex:page>
customcontroller
-------------------
public String testValue { get; set; }
public PageReference gotoNextPage() {
testValue='TestValue set in VF page A';
// set the next page to VF page B
PageReference page = new PageReference('/apex/pageB');
return page;
}
Hence, when I navigate to pageB, I would like to see Test Value:TestValue set in VF page A. Again, I don't want the URL to be /apex/pageB?testValue='TestValue set in VF page A'. Is it possible to do using VF or apex? I might be missing something simple as well. Thanks for your time to help me.

Just a shot in the dark here but is
PageReference page = Page.pageB;
any different to:
PageReference page = new PageReference('/apex/pageB');
?
Whenever I'm linking pages in this way I use the first method to generate a page reference. I'm wondering if the second way (your way) forces the page to create a new instance of your controller instead of reusing the same one.

Hi,
If your two pages use the same controller then all you have to do is set a class variable as you have done. This won't go via the URL.
Is your code not working ?
Hi,
I am not getting any value in the VF page B at all. It is just a blank string ' '.
Thanks
Can you try this:
get rid of 'testValue =' line in custom controller
replace {!testValue} with <apex:outputText value="{!testValue}"/> in second page
above the command button put
<apex:inputText value="{!testValue}"/> in first page
Run it. Then fill in the box on the first page and click the button. You should get the value in the second ?
As long as the controller is the same for both pages it should work.
I just tried using the code from your message (with addition of <apex:form> which is needed for pageA to save)
and it worked as expected.
You must be doing something different in your actual test case.
