multiple dropdown

Hi, i can't tell you exact issue as i cant see whole code here and what values you are passing. But just make sure seleceted value should also exist in choice values array. try to debug the ui and see what's happening once you select anything from the drop down.

a!multipleDropdownField(
                disabled: if(
                  or(
                    not(
                      fv!item.category_txt = cons!CR_APP_SC_GENERAL_SPECIFIC_LAB_VAL[2]
                    ),
                    rule!CR_APP_FN_freezeRecords(
                      crAppSelectedItem_cdt: fv!item,
                      isDisplayed_bool: ri!isEditable_bool
                    )
                  ),
                  true(),
                  false()
                ),
                placeholderLabel: cons!CR_APP_TXT_PLACEHOLDER_VALUE,
                choiceLabels: trim(
                  split(
                    local!facilityChoices.limitIdDescription_txt,
                    ";"
                  )
                ),
                choiceValues: trim(
                  split(
                    local!facilityChoices.limitIdDescription_txt,
                    ";"
                  )
                ),
                value: reject(
                  fn!isnull,
                  {
                    trim(
                      split(
                        fv!item.facility_txt,
                        ";"
                      )
                    )
                  }
                ),
                saveInto: a!save(
                  fv!item.facility_txt,
                  joinarray(
                    save!value,
                    ";"
                  )
                ),

                  )
                ),

Hi there,

According to the error, the choiceValues is null. 
Try printing the choice values on the screen to see if it has a valid set of values, in the desired format.
