KB-2025 Selecting and de-selecting all items in an editable grid results in an incorrect selection list


Selecting the 'select all' checkbox in an editable grid and then deselecting all items causes an incorrect selection list to be stored. See the example below.


This issue has been reported to the Appian Product Team. The reference number for this issue is AN-144124.


Use gridField() instead of gridLayout(). The gridField() function does not exhibit this abnormal behavior.

Alternatively, add the following to the gridLayout() SAIL code per the function documentation.

/* Flatten the selected values so the result is easier to work with */
/* when the select/deselect all option is used in an editable grid */
selectionSaveInto: a!save(local!selected, a!flatten(save!value)),
