Hi Michael,

The create action is called as a result of a form being filled out:

<f:form method="post" action="create" object="{disc}" name="disc"
                onsubmit="return validateNewForm(this)"  
enctype="multipart/form-data">
<f:form.hidden name="numTracks" value="5" property="numTracks"/>
<f:form.hidden name="isNew" value="true" property="isNew" />
<fieldset>
<legend>Artist</legend>
<label for="artist" style="float:left;width:22ex">
                 Enter name of artist:
</label>
<f:form.textbox property="artist" id="artist"  />
</fieldset>
<br />
<fieldset>
<legend>Disc</legend>
<label for="title" style="float:left;width:15ex">
                 Enter disc title:
</label>
<f:form.textbox id="title" size="25" property="title" />
</fieldset>
<br />
<div style="text-align:center">
<f:form.submit class="button" value="Create Disc />
</div>
</f:form>

In my debugging runs, $disc is not NULL while the create action is 
running. (I had that problem for a time, but figured out what I was 
doing wrong for that one.) It does, however, say that $disc is of type 
F3\TrackLibrary_PHP\Domain\Model\Disc_AOPProxy_Development. Not 
surprisingly, saving $disc to $this->disc produces the same type for 
$this->disc. In case it helps, $this->disc is declared as follows:

     /**
      * @var \F3\TrackLibrary_PHP\Domain\Model\Disc
      */
     protected $disc;


The actual error message is this:
#1269616784: The value of argument "disc" must be of type 
"F3\TrackLibrary_PHP\Domain\Model\Disc", but was of type "NULL".
