[TYPO3-mvc] fluid selector - Argument passed to x must be an instance of y, string given

[Christian Essl]

I dumped the object in extbase/classes/Reflection/ObjectAccess.php:

object(Tx_Extensionname_Domain_Model_Lehrgang)#649 (22) {
  ["uid:protected"]=>
  NULL
  ["hidden:protected"]=>
  NULL
  ["titel:protected"]=>
  string(4) "title"
  ["alias:protected"]=>
  NULL
  ["allgemein:protected"]=>
  NULL
  ["lehrinhalte:protected"]=>
  NULL
  ["ausbildung:protected"]=>
  NULL
  ["finanzierung:protected"]=>
  NULL
  ["htmlTitle:protected"]=>
  NULL
  ["htmlDescription:protected"]=>
  NULL
  ["htmlKeywords:protected"]=>
  NULL
  ["htmlRobots:protected"]=>
  NULL
  ["htmlSitemapChanges:protected"]=>
  NULL
  ["htmlSitemapPriority:protected"]=>
  NULL
  ["ausbildungsSchwerpunkt:protected"]=>
  NULL
  ["themenSchwerpunkt:protected"]=>
  object(Tx_Extbase_Persistence_ObjectStorage)#631 (3) {
    ["warning:private"]=>
    string(208) "You should never see this warning. If you do, you probably used PHP array functions like current() on the Tx_Extbase_Persistence_ObjectStorage. To retrieve the first result, you can use the getFirst() method."
    ["storage:protected"]=>
    array(0) {
    }
    ["isModified:protected"]=>
    bool(false)
  }
  ["kurs:protected"]=>
  object(Tx_Extbase_Persistence_ObjectStorage)#650 (3) {
    ["warning:private"]=>
    string(208) "You should never see this warning. If you do, you probably used PHP array functions like current() on the Tx_Extbase_Persistence_ObjectStorage. To retrieve the first result, you can use the getFirst() method."
    ["storage:protected"]=>
    array(0) {
    }
    ["isModified:protected"]=>
    bool(false)
  }
  ["_localizedUid:protected"]=>
  NULL
  ["_languageUid:protected"]=>
  NULL
  ["pid:protected"]=>
  NULL
  ["_isClone:private"]=>
  bool(false)
  ["_cleanProperties:private"]=>
  NULL
}

For some reason all the fields after "titel" have become NULL. (titel is the first input in the formular) This only seems to happen, when the ausbildungsSchwerpunkt-selector is in the formular. When I remove it, it saves all the fields normally and no error is thrown...

The formular:

Sounds strange indeed. I suspect a problem in the Property Mapper or the data given to it. Do you have this property used in other form fields too? Do you have a way to dump the POST'ed data array? You should see an integer in the ausbildungsSchwerungen value.
