      Description

      Steps to Reproduce

      https://zkfiddle.org/sample/1fk5tle/2-missing-listbox-size-event-CE

      Run in a CE context

      Click button

       

      Current Result

      Listbox adds the new rows, but doesn't resize (not flexing). The listbox grows outside of the screen incorectly.

      Expected Result

      Listbox just normally trigger a flex sync and flex calculation is applied

      Debug Information

      The interval_added internal event need to trigger partial invalidate

      https://github.com/zkoss/zk/blob/678daef08e6005f7e1acb4036679868e8c2898fa/zul/src/org/zkoss/zul/impl/ListboxDataLoader.java#L118

      This only happen if there is no other even triggering a full invalidate in the execution, and if the added rows are > invalidate threshold of the listbox, and if the original listbox wasn't empty

                          return result;
                      }
