[TYPO3-mvc] problems with a property in my model - all others are fine - property is of typeTx_Extbase_Persistence_LazyObjectStorage

[Stephen Bungert]

I have a model that has several fields of type "inline".

It doesn't work in the frontend - backend is fine.

I know it finds the correct record - I have debugged the queries ExtBAse 
makes and cann see that it finds the record, but using any property from the 
record causes an error. For eyample, if I use {item.preview.title} in my 
template I get the error:

Call to undefined method 
Tx_Extbase_Persistence_LazyObjectStorage::getTitle()

I have lots of other similar properties to preview and they all work, but 
preview doesn't.

here is the tca for my preview property:

====
  'preview' => array(
   'exclude' => 1,
   'label' => $sbp2Label . 'preview',
   'l10n_mode' => 'mergeIfNotBlank',
   'config' => array(
    'type' => 'inline',
    'foreign_table' => 'tx_sbportfolio2_domain_model_image',
    'foreign_field' => 'itempreview',
    'minitems' => 0,
    'maxitems' => 1,
    'appearance' => array(
     'collapse' => 0,
     'levelLinksPosition' => 'top',
     'showSynchronizationLink' => 1,
     'showPossibleLocalizationRecords' => 1,
     'showAllLocalizationLink' => 1,
     'newRecordLinkAddTitle' => 1,
     'expandSingle' => 1,
     'newRecordLinkAddTitle' => 1,
     'enabledControls' => array(
      'info' => true,
      'new' => true,
      'dragdrop' => false,
      'sort' => false,
      'hide' => true,
      'delete' => true,
     ),
    ),
   ),
  ),
====

in my model class I have defined prview like this:


====
 /**
  * An image to be used as a preview of the item.
  *
  * @var 
Tx_Extbase_Persistence_ObjectStorage<Tx_SbPortfolio2_Domain_Model_Image>
  * @lazy
  */
 protected $preview;
====

in my classes initStorageObjects() methods I have the following line

====
$this->preview = new Tx_Extbase_Persistence_ObjectStorage();
====

My methods for getting and setting look like this:

====
 /**
  * Adds a preview Image
  *
  * @param Tx_SbPortfolio2_Domain_Model_Image $preview
  * @return void
  */
 public function addPreview(Tx_SbPortfolio2_Domain_Model_Image $preview) {
  $this->preview->attach($preview);
 }

 /**
  * Removes a preiew Image
  *
  * @param Tx_SbPortfolio2_Domain_Model_Image $previewToRemove The Image to 
be removed
  * @return void
  */
 public function removePreview(Tx_SbPortfolio2_Domain_Model_Image 
$previewToRemove) {
  $this->preview->detach($previewToRemove);
 }

 /**
  * Returns the preview
  *
  * @return 
Tx_Extbase_Persistence_ObjectStorage<Tx_SbPortfolio2_Domain_Model_Image> 
$preview
  */
 public function getPreview() {
  return $this->preview;
 }

 /**
  * Sets the preview
  *
  * @param 
Tx_Extbase_Persistence_ObjectStorage<Tx_SbPortfolio2_Domain_Model_Image> 
$preview
  * @return void
  */
 public function setPreview(Tx_Extbase_Persistence_ObjectStorage $preview) {
  $this->preview = $preview;
 }
====

I think the problem is in my clas somewhere, I have recently changed the 
code, and before it used to work  in the FE:

Before get and set preview used to return and accept as an argument an 
object of type Tx_SbPortfolio2_Domain_Model_Image, but now I have modified 
it like my other properties to Tx_Extbase_Persistence_ObjectStorage.


Does anyone have any tips about how to solve this? Or see what I have done 
wrong?

Thanks.
