Servus,
ich bin gerade dabei mir eine Komponente zusammen zustricken und habe ei Problem mit der Pagination,
Als erstes mal mein Code:
Das Model:
Der Wiev
und die default:
Die blätter Funktion als "Start 123 Ende" Funktioniert zwar, allerdings kann ich die Seite eins nachdem ich anfange mit dem blättern nicht mehr anklicken...
hier mal die komponente zur verdeutlichung: http://feuerwehr-suchmaschine.de/tv-tipps.html.
Vielen Dank erstmal
Grüße mirko
