changed the copyFormValues..(), the deleteAttachment method now doesnt call this method, otherwise all fields will be blank.instead of using hardcoded default content id, makes the call to getDefaultToolContentId
a new instance of NBMonitoringForm is instantiated in the execute method to ensure that we are using a new form each time this starter action is called
modified the validate method, the validate method doesnt check whether the title or content fields are empty, because the fckeditor buts in <br> tags even when there is no content
