I have built a plugin for CKEditor where I load a json feed and then its values are entered into the elements of a dialog window. When I launch the dialog window again trying to load a different feed the elements contain the values from the first feed. But if I click OK then it passes the correct values of the second feed into the document. For some reason the values of the elements are not refreshed. Can you tell me how can I refresh them so each time they will contain the data of the current feed?
