    The latest 2016 version treelist some time doesn't return the right data when apply the filter on column.

    Here's the code which you can repeat that bug. When I apply a filter on column ClassSecurity start with "U", the data is incorrect. But the old 2015 version is good.

    2016 version

    2015 version

    Hello Congyuan,


    Actually the 2016 version demonstrates proper operation of the widget rather than 2015 version. Here is the reason for the above statement:


    1. If you run both examples without filtering both shows that there is only one root level item

    2. When you filter:

     - 2015 shows 2 root items which is incorrect, there should be still only 1 root item

     - 2016 shows 1 root item, i.e the expected result. 


    There is another issue - the data collection have items with duplicate id/xml_seq values:


    parentId: "||10||000"
    xml_seq: "||10||000||S"

    parentId: "||10||000"
    xml_seq: "||10||000||S"
    ClassSecurity: "US Dollar Cash"


    and when you filter only one of them shows up in the widget as it expects the id field to have unique values.
