I have a visualforce page that has a date input.  This page is embedded in a object page detail.

My goal is to have them select a date - click the button which takes them to a new pop-up window / visualforce page where they can enter time / hours.

Depending on which object the first visualforce page is embedded, I want to pass that objects recordID to the controller, but I am getting nothing - getting "null".  I have tried <apex:param and <apex:inputhidden and neither work.

The workflow is:

•      PARENT OBJECT (CCI_project__c) has an embedded VF page called "terlproject"
•      TERLPROJECT has a form with a date picker.  Once the button is clicked, the controller is "OpenTimeEntry"
•      All OpenTimeEntry does is gather the parameters (date and objectID) and pass it to a new VF page called teGridView
•      TEGRIDVIEW has a controller (teGridClass) that pulls data and populates the VF page "teGridView"

Can anyone help?  Below is screen shots and code:

1.  embedded visualforce page "terlProject"   In this case, It is on a custom object called "CCI_Project__C" and I am trying to pass the Date and REcord ID - the date is passing fine - the record ID is not (I display it on the VF page so I know the ID exists)


The code for the Visualforce page is: 

<apex:page Standardcontroller="CCI_Project__c" extensions="openTimeEntry">
    <apex:form >
        <!-- Variables go here -->
        

        <!-- Input Buttons here -->
        <apex:pageBlock >
            <apex:pageBlockButtons >
                <b>Date</b><apex:inputfield value="{!dum.dateOne__c}"/>
                <apex:inputHidden value="{!CCI_Project__c.ID}" id="projID"/>
               Project. <apex:outputField value="{!CCI_Project__c.id}"/>
                <apex:commandButton value="Enter Time" action="{!fetchPage}">
               <!-- <apex:param name="projID" value="{!CCI_Project__c.ID}" assignTo="{!projID}"/>-->
                </apex:commandButton>
            </apex:pageBlockButtons>
        </apex:pageBlock>
    </apex:form>
    
    <!-- Related List Displays here -->



</apex:page>

Once clicked, I call the controller class "openTimeEntry" - you will see i have tried various ways of "getting" the ProjectID - but debug shows null.

public class openTimeEntry {
public dummyTable__c dum{get;set;}
public ID projID{get;set;}
public cci_Project__c co {get; set;}
private Date uDate; 

public openTimeEntry(ApexPages.StandardController controller) { 
    Date uDate = Date.valueOf(System.Now());
    dum=new dummyTable__c();
    System.debug('ProjID: '+projID);
    }

public PageReference fetchPage(){
      
      String testDate = String.valueof(dum.dateOne__c);
      if(testDate==null) {
          uDate = Date.today();
      }else{
          uDate = dum.dateOne__c; 
       }

              System.debug('openTimeEntryTestDate'+testDate);
              System.debug('openTimeEntrydumDate'+dum.dateOne__c);
              System.debug('openTimeEntryuDate'+uDate);
              System.debug('ProjectID----'+projID+co);
      
        pageReference teGridView = new PageReference('/apex/teGridView?uDate='+uDate+'&projectID='+projID);
        return teGridView ;
    
    }
 
  
}

Then I re-direct to the teGridView which has a controller class teGridClass

Here is the page, followed by the class.
