A simple example based on what's in the VF docs :


<apex:page standardController="Account" extensions="myControllerExtension">
    <apex:form >
        <apex:PageBlock >
            <apex:pageblockSection >
                <apex:inputField value="{!account.name}"/>  
                <apex:inputfield value="{!account.website}"/>
            </apex:pageblockSection>
            <apex:commandButton value="Custom Action" action="{!customsave}"></apex:commandButton>
        </apex:PageBlock>
    </apex:form>
</apex:page>

... and the controller extensions :


public class myControllerExtension {

    private final Account acct;
   
    // The extension constructor initializes the private member
    // variable acct by using the getRecord method from the standard
    // controller.
    public myControllerExtension(ApexPages.StandardController stdController) {
        this.acct = (Account)stdController.getRecord();
    }
   
    public PageReference customsave() {
        acct.website = 'somenewvalue';
        return null;
    }
}

I would image that the account object that's being held in the viewstate would get updated and that after the page refresh it would simply display the new in-memory value ... but it doesn't. In fact this code does nothing at all.

Am I thinking too much in 'managed beans' terms here ? What am I missing ?


Thanks,
