Reload Visualforce Page After Update

Question

I have a Visualforce page on a custom object that has a commandButton to update a field on the custom object. When that field is updated, a Process fires that then creates a case based on the information in the custom object record. All works fine. However, I would like to refresh the page once the Process fires. Is this possible?

CommandButton:

<apex:commandButton rendered="{!(CC.Create_Case__c == false)}" value="Create Case" action="{!CreateCase}" style="background:#d699ff; padding: 5px 10px 5px 10px"/>

Controller:

public with sharing class VF_Controller_CreateCampaignCase{

public Campaign_Create_Request__c CCR;

    public VF_Controller_CreateCampaignCase(ApexPages.StandardController myController){
        this.CCR = (Campaign_Create_Request__c)myController.getRecord();
    }

    public Void CreateCase() {
            CCR.Create_Case__c = true;
            update CCR;
    }
}

Thanks everyone. I got my problem resolved by changing the Void method in my controller to a PageReference method and then adding a redirect back to my current page. Thanks for all your help! Updated working code for my controller is below:

public with sharing class VF_Controller_CreateCampaignCase{

    public Campaign_Create_Request__c CCR;

    public VF_Controller_CreateCampaignCase(ApexPages.StandardController myController){
        this.CCR = (Campaign_Create_Request__c)myController.getRecord();
    }

    public PageReference CreateCase() {
        CCR.Create_Case__c = true;
        update CCR;

        PageReference tempPage = ApexPages.currentPage();            
        tempPage.setRedirect(true);
        return tempPage;
    }
}

If your commandbutton fires an action in your controller, you should just need to make that method return a PageReference, and then return null

Such as:

public pageReference updateFields() {
    // do some magic
    return null;
}

(and then the action on your commandbutton is something like:

<apex:commandButton action="{!updateFields}" value="Update!" />

)

Edit: That is, unless you already have all this in place and you only want to reload the page once your controller "knows" that the process has fired. Which might be more complicated.

You can do this using <apex:actionFunction> below is the code .

<apex:pageblocksection id="test">
<apex:actionfunction id="refresh" rerender="test"/>
<apex:commandButton reRender="test" />
</apex:pageblocksection>
