Does additional arguments break Auto-modal?

Hello,

after reading some entries about ctools, modal, automodal, ctools_automodal etc. I try to create my first ajax modal applications.

Out of the box by changing the menu_item, the first form is getting called as it should.

Here it is:

    $items['convert/bet/%'] = array(
            'type' => MENU_CALLBACK,
            'page callback' => 'drupal_get_form',
            'access callback' =>'user_access',
            'access arguments' => array('save as group content'),
            'page arguments' => array('organic_fussball_convert', 2),
            'modal' => TRUE,
            
    );

function organic_fussball_convert($form, &$form_state, $node) {
	  drupal_set_title(t('Möchten Sie diese Wette für Ihre Mitglieder aktivieren?'));
	  //Take the groups from organic groups
	  $gids = og_get_groups_by_user();
	  foreach($gids as $gid){
	  	foreach($gid as $key=>$val){
	  		$keys[] = $key;
	  	}
	  }
	 // drupal_set_message("GID: ".'<pre>'.print_r($keys,1).'</pre>');
	  // Just store the entire $node object in a custom form property.
	  $node = node_load($node);
          
	  if(isset($node->og_group_ref['und'])){
	  $gruppenrefs = $node->og_group_ref['und'];
	  foreach($gruppenrefs as $gruppenref){
	  	foreach ($gruppenref as $key => $value){
	  		$target_id[]= $value;
	  	}	
	  }
	  $intersection = array_intersect($keys,$target_id);
	  }
	 if(!empty($intersection)) {
	  	drupal_set_message(t('Sie haben diese Wette schon aktiviert.'));
	  	drupal_goto('naechste-wetten');
	  }
	  else{
	  
	  $form['#node'] = $node->nid;
	  //drupal_set_message("Node: ".'<pre>'.print_r($intersection,1).'</pre>');
	  
	  // An example form field that we'll use to update the node's title.
	  $form['new_title'] = array(
	    '#title' => 'Title',
	  	'#type' => 'hidden',
	    //'#type' => 'textfield',
	    '#default_value' => $node->title,
	  );
	  $form['new_gids'] = array(
	  	'#title' => 'Gruppen-IDS',
	  	//'#type' => 'textfield',
	  	'#type' => 'hidden',
	    '#default_value' => $keys
	  );
	  $form['cancel'] = array(
	  		'#type' => 'button',
	  		'#value' => t('Cancel'),
	  		//'#prefix' => '&nbsp; &nbsp; &nbsp;',
	  		'#attributes' => array('onClick' => 'history.go(-1); return true;'),
	  		'#post_render' => array('change_button_type'),
	  );
	  
	  $form['submit'] = array(
	    '#type' => 'submit',
	    '#value' => t('Aktivieren')
	  );
	
	  return $form;
	}
}
function change_button_type($markup, $element) {
		$markup = str_replace('type="submit', 'type="button', $markup);
		return $markup;
	}	
function organic_fussball_convert_submit(&$form, &$form_state) {
	  $node_nid = $form['#node'];
          $node = node_load($node_nid);
	  $node->title = $form_state['values']['new_title'];
	  $node->og_group_ref[LANGUAGE_NONE][] = array
	  (
	  		'target_id' => $form_state['values']['new_gids'],
	  );
	  
	  node_save($node);
	  drupal_goto('convert/wager/'.$node->nid);
	
	}

But when I click on submit, the next function, called with "drupal_goto('convert/wager/'.$node->nid);" (see las line above) comes as a fault with a 200 response. Code is as follows:

 $items['convert/wager/%'] = array(
    		'type' => MENU_CALLBACK,
    		'page callback' => 'drupal_get_form',
    		'access callback' =>'user_access',
    		'access arguments' => array('save as group content'),
    		'page arguments' => array('organic_fussball_wager', 2),
                'modal' => TRUE,
    );

function organic_fussball_wager($form, &$form_state, $node) {
            drupal_set_title(t('bla'));
            //Take the groups from organic groups which belongs the current user
            $gids = og_get_groups_by_user();
            foreach($gids as $gid){
                    foreach($gid as $key=>$val){
                            $keys[] = $key;
                    }
            }

            $gruppe=  node_load($key);
            if(isset($gruppe->field_group_user['und']['0']['value'])){
           $spielfuehrer1 = $gruppe->field_group_user['und']['0']['value'];
            }
             if(isset($gruppe->field_group_user['und']['1']['value'])){
           $spielfuehrer2 = $gruppe->field_group_user['und']['1']['value'];
             }
            // Just store the entire $node object in a custom form property. Easy.
            $node = node_load($node);

            $nnid = $node->nid;
            if(!empty($spielfuehrer1)){
                $uid_base1 = '';
                $uid_base1=$spielfuehrer1.','.$nnid;
            }
            else {$uid_base1 = 'leer';}
            if(!empty($spielfuehrer2)){
                $uid_base2='';
                $uid_base2=$spielfuehrer2.','.$nnid;
            }
            else{$uid_base2 = 'leer';}
            if(isset($node->og_group_ref['und'])){
                    $gruppenrefs = $node->og_group_ref['und'];
                    foreach($gruppenrefs as $gruppenref){
                            foreach ($gruppenref as $key => $value){
                                    $target_id[]= $value;
                            }
                    }
                 //   drupal_set_message("Wenn man dann die Referenzen der webform ausgibt: ".'<pre>'.print_r($target_id,1).'</pre>');
                    $intersection = array_intersect($keys,$target_id);
                 //   drupal_set_message("Und nach der Schnittstelle zwischen der OG des aktiven Nutzers und den schon eingetr
                 //       agenen Referenzen der Webform schaut: ".'<pre>'.print_r($intersection,1).'</pre>');
                    $uid_tupel = organic_fussball_test_wetteinsatz();
                  //  drupal_set_message("Dann noch die Abfrage des Wetteinsatzes als String: ".'<pre>'.print_r($uid_tupel,1).'</pre>');
                    //hat der Nutzer schon die Wette aktiviert?
                    if (in_array($uid_base1,$uid_tupel) || in_array($uid_base2,$uid_tupel)) {$da = 1;}
                    else{$da=0;}
                    
            }
            if(!empty($intersection) && $da =='1') {
                    drupal_set_message(t('Diese Wette wurde für Ihre Gruppe aktiviert.'));
                    drupal_goto('naechste-wetten');
            }
            else{

            $form['#node'] = $node;
            

            // An example form field that we'll use to update the node's title.
            $form['new_title'] = array(
                            '#title' => 'Title',
                            '#type' => 'hidden',
                            //'#type' => 'textfield',
                            '#default_value' => 'Wetteinsatz',
            );
            $form['new_gids'] = array(
                            '#title' => 'Gruppen-IDS',
                            //'#type' => 'textfield',
                            '#type' => 'hidden',
                            '#default_value' => $keys
            );
            $form['related_bet'] = array(
                            '#title' => 'Related bet',
                            '#type' => 'hidden',
                            '#default_value' => $node->nid

            );
            $form['body'] = array(
                            '#type' => 'textarea',
                            '#description' =>'bla
                                                                    ',
                            'default_value' => ''				
            );

            $form['submit'] = array(
                            '#type' => 'submit',
                            '#value' => t('Wetteinsatz bestätigen')
            );

            return $form;
    }
}

So is there a problem with the "drupal_go_to" or with the additional argeument? Or shall I use ctools without this module?

Any help is appreciated!

Thx in advance,
