    ListGrid Criterion of Array-Field

    Hello dear developers.
    I have a field in a DataSource of type Array. How do I create a Criterion that checks if there is a XXX value in this field. I tried OperatorId.CONTAINS and OperatorId.ICONTAINS and OperatorId.EQUALS, but they don't work.

    In the List Grid, this field is invisible and I need to set the filter programmatically.
    If I make the field visible and enter the value I need into the filter field, then it is filtered as it should be.
    In this case, the Criteria value for the ListBox is
    criteria {
    fieldName: "users"
    operator: "iContains"
    value: "266"

    if you comment out the lines in the example
             String myUserID = "2";
             filter.addCriteria("users", OperatorId.ICONTAINS, myUserID);
    and insert a line instead
    then when you manually enter the filter in the "users" field, the filter works correctly


      It seems like you are looking for DataSourceField.multiple:

      The docs here have an extensive description of how criteria works on multiple:true fields.


        thank you very much!
        everything worked


          dear developers
          , in firefox esr version 102.12, I get the following warning. And the filter I installed doesn't work

          9:11:59.745:IBLR3:WARN:TextItem:isc_TextItem_12[users]:compareValues - this is a multiple FormItem but compareValues was called with a non-null first argument `value1` that is not an array. ISC_Core.js:1286:136

          could you explain in more detail what the problem is?

          I set the filter this way
          AdvancedCriteria filterProjects = new AdvancedCriteria(OperatorId.AND, new Criterion[]{});
                String myUserID = EvolutionServer.getUserData(CONSTANT._ID);
                filterProjects.addCriteria(CONSTANT.USERS, OperatorId.EQUALS, myUserID);
          The "users" field is defined as
          DataSourceField users = new DataSourceField(CONSTANT.USERS, FieldType.CUSTOM);
          I have checked the data received from the server and there is no empty data for the "users" field


            You may have misread the error message. It's not saying you have an empty value, it's saying you have a value that is not an Array.

            The value for a multiple field must be an Array.


              I checked the data received from the server again, and there is no non-array data for the "users" field
              I will try to track the error in the debugger and report the result later.



                I think Isomorphic means that your

                [B]String[/B] myUserID = EvolutionServer.getUserData(CONSTANT._ID);
                filterProjects.addCriteria(CONSTANT.USERS, OperatorId.EQUALS, [B]myUserID[/B]);
                is not an Array.

                Best regards


                  thank you very much for the hint, but it also did not lead to a positive result.

                  To my great shame, the error appeared due to data caching. After clearing the cache, it disappeared.
