im currently using a modeladmin to manage a list of events

because the result page only showed the id, i added a $summary_fields to my DataObject

	static $summary_fields = array(
		"Titel"=>"Titel"	
	);

but when i now press Search i get an error

Warning: "array_fill() [function.array-fill]: Number of elements must be positive" at line 743 of /var/www/example.com/page/cms/code/ModelAdmin.php

i also tried

function summaryFields() {
      return array("Titel"=>"Titel");
}

but this changed nothing

any solutions for my problem?

Hi,

could you please provide the full Code of your Class.
The static var is defined correctly. The error has to be somewhere else.

Greets,

VAAdmin:

class VAAdmin extends ModelAdmin {
	public static $managed_models = array(
		'VAKategorie','VAEintrag'
	);
	
	static $url_segment = "va";
	static $menu_title = "Veranstaltungen";
}

VAEintrag:

<?php

class VAEintrag extends DataObject {
	static $db = array(
		"Titel"=>"Varchar(50)",
		"Kontakt"=>"Text",
		"Beschreibung" => "Text"
	);
	
	static $has_one = array(
		"Kategorie" => "VAKategorie"
	);
	
	function ShortenDesc($l=200) {
		$desc = $this->Beschreibung;
		if(strlen($desc) > $l) {
			return substr($desc,0,$l)."...";
		} else {
			return $desc;
		}
	}
	
	static $searchable_fields = array(
		"Titel",
		"Kontakt",
		"Beschreibung"
	);
		
	static $summary_fields = array(
		"Titel"=>"Titel"	
	);
		
	function getCMSFields() {
		$categories = DataObject::get('VAKategorie');
		if($categories) {
			$dropdowndata = $categories->toDropdownMap('ID','Titel','(Eine Kategorie aussuchen)',true);
		}	
	
		return new FieldSet(
			new TextField("Titel"),
			new TextareaField("Kontakt"),
			new TextareaField("Beschreibung"),
			new DropdownField("KategorieID","Kategorie",$dropdowndata)
		);
	}
}

here you are.

sorry, didn't see it

It has to be this way:

static $summary_fields = array('Titel');

Your code example works for me with both array("Titel") and array("Titel" => "Titel") in 2.4.3
