CKEditor is duplicating a field -

so original problem needed rid of img style attribute on images in ckeditor. i found code trick: if (ckeditor.instances['field_id_4']) { ckeditor.remove(ckeditor.instances['field_id_4']); } ckeditor.replace('field_id_4',{ allowedcontent: 'img[!src,alt,width,height]{float};' + 'h1 h2 div' }); but when top condition there. now see though, ckeditor duplicated... anyone know how fix this? you should use editor.destroy() instead of ckeditor.remove private method. something like: if (ckeditor.instances['field_id_4']) { ckeditor.instances['field_id_4'].destroy(); } ckeditor.replace('field_id_4',{ allowedcontent: 'img[!src,alt,width,height]{float};' + 'h1 h2 div' });

Sitecore Event Queue - Can I delay events? -

sitecore has nice event queueing system persisted database. can define custom events . i need able raise event has delay before it's processed. possible? i use other queueing system ( apachemq ?), nice use built in sitecore 1 if possible. as far know not possible delay event directly. there way custom code want executed delay. you create custom event. in custom event handler use sitecore jobmanager execute specific method want start delay. using sitecore jobmanager able delay execution of method passing additional parameter "initialdelay". var options = new joboptions("jobname", "category", "sitename", "object instance contains method execute", "methodname") { initialdelay = timespan.fromminutes(5.0) }; jobmanager.start(options); you can use execute method on cd server delay, after triggering cms server using remote events. see this link more info sitecore jobs.
