"Call to member function on a non-object" on and object?!

Well, I have the following (simplified) classes.
[size=9pt][color=green]<?php
include_once("Wrapper.php");
include_once("Declarations.php");

class ApplicantData extends Wrapper  {

var $fnmFile; // Representation of the Fannie Mae File

                ...
var $declarations; //One Object per Applicant
...

* breaks apart the other rows like normal
* A lot of the same functionality of loan app

function ApplicantData($fnmFile = '',$row,$rowNumber){
parent::Wrapper($fnmFile);
$this->row = $row;

$this->constructDeclarations();
...
}

The ... are lines taken out that are not relevant to the problem. Anyways, as you can see, I put in the print_r line in ApplicantData object because of the error I was getting, and here's the output:

[size=9pt][color=red]declarations Object ( [row] => 08A555551212NNNNNNNNN01YY101 [id] => [loanAppId] => [applicantSSN] => [anyOutstandingJudgments] => [declaredBKpast7Years] => [propForclosed7Years] => [partyLawSuit] => [directlyOrIndirectlyObligatedLoan] => [presentlyDeliqFedDebt] => [obligatedPayAlimonyChildSupport] => [downPaymentBorrowed] => [comakerEndorserNote] => [USCitizen] => [permResidentAlien] => [intendToOccupy] => [ownershipInterest] => [whatTypeOfProperty] => [howDidYouHoldTitle] => )
Fatal error: Call to a member function on a non-object in /var/www/localhost/htdocs/basebuild/custom/fanniemae/ApplicantData.php on line 687[/color][/size]

Now how in the world is it an object when I print it out and then in the very next line it's no longer an object? Thanks.

[makeshift_theory]

What is on line 687 exactly?

[wesblake]

Oops, sorry. Line 687 is the line in ApplicantData towards the bottom under the print_r statement:
$this->declarations->setLoanAppId($this->loanAppId);

[makeshift_theory]

The way you have it coded here :  $this->declarations->setLoanAppId($this->loanAppId);
means that there is setLoadAppId object within the declarations property in which there is not from what I could see. 

here you have: [code]  function constructDeclarations(){
        $row = $this->getSegmentRow($this->SEGMENT_DECLARATIONS);
        $Declaration = new Declarations($row);
            if($Declaration->getApplicantSSN() == $this->getApplicantSSN()){
              $this->declarations = $Declaration;
        }
      }[/code]

This looks like it would make a new instance of the Declarations Object but you don't seem to call that before $this->declarations->setLoanAppId($this->loanAppId);  therefore I think it's not seeing that setLoadAppId is a method of the Declarations class.  Make sense? ???

[wesblake]

The setLoanAppId is a function in the Declarations object, and the constructDeclarations() function is called in the constructor for the ApplicantData object, so I would think everything would be ok.

[makeshift_theory]

I see the method: [code]      function ApplicantData($fnmFile = '',$row,$rowNumber){
        parent::Wrapper($fnmFile);
        $this->row = $row;
        $this->rowNumber = $rowNumber;
        //Call construct methods below
        ...
        $this->constructDeclarations();
        ...
      }[/code]
However, I do not see where you are constructing this.  You have "Call construct methods" however to initalize that the way it is written, you would have to call ApplicantData first.  If you add a function:
[code]function __construct() { $this->declaration = $this->construct Declarations(); }[/code] That should iniatilize the object.  Do you have a __construct method?

[wesblake]

I'm sorry, I keep leaving information out. There is actually an overall object called FannieMae which has a bunch of objects it holds. One of these object is ApplicantData, FannieMae is constructing ApplicantData (there are way to many objects to post). In turn, ApplicantData has a bunch of object it contains, one of which is this Declarations object.
I am trying to get the series to save, so I call the save function of FannieMae which successfully calls save on all of it's other objects (which do not have more objects of their own like ApplicantData does so they are simple sql calls) and then when it gets to ApplicantData's save function, the sql statement for that is also executed, but it fails at this call trying to call save on it's object(s). Does this clarify?

[makeshift_theory]

To be honest it's really hard to tell what the problem is without all of the code structure.  The problem is the iniatilization of the object no question there, so somewhere in your code you need to look where that problem is occuring.
