javascript - How to workaround jQuery UI droppable bug where over/out do not fire if draggable element is dragging before droppable bound -


i have list of draggable objects , droppable target. view housing droppable target gets created , rendered when dragging starts. i've attached images highlighting desired action bottom of post.

the issue jquery ui appears have bug. post: droppable items not displaying hoverclass if shown during drag operation seems corroborate belief.

i have code enables draggable-ness:

this.$el.find('.videosearchresultitem ').draggable({     helper: function() {          var helper = $('<span>', {             text: videosearchresultitems.selected().length         });          return helper;     },     appendto: 'body',     containment: 'dom',     zindex: 1500,     cursorat: {         right: 20,         bottom: 30     },     start: function (event, ui) {          var draggedvideoid = $(this).data('videoid');         var draggedvideo = videosearchresultitems.get(draggedvideoid);         draggedvideo.set('selected', true);         $(ui.helper).addclass("ui-draggable-helper");      } });

my program has event listener video search result becoming selected. when 1 becomes selected, 'additems' view renders , transitions in.

this.listento(videosearchresultitems, 'change:selected', function (changeditem, selected) {      if (selected && this.additemsview === null) {         this.additemsview = new additemsview();         this.$el.append(this.additemsview.render().el);         this.additemsview.show();     }  });

additemsview initializes droppable during render:

this.$el.find('i.droppable').droppable({     hoverclass: 'icon-drop-hover',     tolerance: 'pointer' });

unfortunately, if draggable dragging when view rendered -- hoverclass fails 'over' event.'

i'm wondering if there's workaround this? don't see one.

the solution set draggable element's "refreshpositions" option true. causes inform droppable if droppable created late.
