[SalesForce] Pass Id from Visualforce Email template to Controller

I am trying to pass an id through a Visualforce email template component to its class.

The class creates a wrapper, to combine two objects records into one list. The two objects lists have a common ID (Account) which i am trying to pass through the Email Component…

<apex:attribute type="Id" name="recordId" description="Record ID" assignTo="{!recId}" />

I am having issue with the Order of Execution in page loads – I am aware that my controller is not reading the value, because the constructor is fired first.

I have looked at several posts which confirm this behaviour, and I have tried he suggestions, however I have not managed to solve this issue.

How do I pass the recId to the constructor?

UPDATE: The original pasted code was a snippet, I have added some more code/information to be more specific as to what I am trying to achieve.

APEX:

public class CustomerStatementTableEmailController {

    public Id recId {get;set;}

    public List <Delivery_Note__c> notDue {get;set;}  //less than 30
    public List <Delivery_Note__c> notDueC {get;set;}  //less than 30

    public class Wrapper implements Comparable {

    public Delivery_Note__c note {get; private set;}
    public Remittance_Advice__c remittance {get; private set;}
    public String dataType {get;private set;}

    public Wrapper(Delivery_Note__c n) {
        note = n;
        dataType = 'note';
    }

    public Wrapper(Remittance_Advice__c r) {
        remittance = r;
        dataType = 'remittance';
    }

    public Integer compareTo(Object instance){
        Wrapper that = (Wrapper)instance;
        if (this.calculatedDate > that.calculatedDate) return 1;
        if (this.calculatedDate < that.calculatedDate) return -1;
        return 0;
    }
}

    public List<Wrapper> wrappers {get; private set;}

    public CustomerStatementTableEmailController() {

        List<Delivery_Note__c> notes = [
            SELECT id,name,Balance__c,Transaction_Amount__c,Transaction_Date__c,Transaction_Number__c,Transaction_Type__c,
                Transaction_Balance__c,ABM_Invoice_Amount__c,ABM_Credit_Note_Amount__c,zTransactionBalanceForStatement__c
            FROM Delivery_Note__c
            WHERE order__r.AccountId = :recId
        ];

        wrappers = new List<Wrapper>();

        for (Delivery_Note__c note : notes) {
            wrappers.add(new Wrapper(note));
        }

        List<Remittance_Advice__c> remittances = [
            SELECT id,Name,Account__r.id,Date__c,Remittance_Total_Credit__c,Remittance_Total_Debit__c
            FROM Remittance_Advice__c
            WHERE Account__r.id = :recId
        ];

        for (Remittance_Advice__c remittance : remittances) {
            wrappers.add(new Wrapper(remittance));
        }

        wrappers.sort();

        notDue = [
            SELECT id,Invoice_Total_Amount_Including_GST__c,Balance__c,recordType.Name,Transaction_Balance__c FROM Delivery_Note__c
            WHERE zAgeTrialBalance__c = 'Current'
            AND recordType.Name = 'Delivery Note / Invoice'
            AND order__r.Accountid = :recId
            ];
        notDueC = [
            SELECT id,Credit_Note_Total_Including_GST__c,Balance__c,Transaction_Balance__c FROM Delivery_Note__c
            WHERE zAgeTrialBalanceCredit__c = 'Current'
            AND recordType.Name = 'Credit Note'
            AND order__r.Accountid = :recId
            ];
    }
}
