SAP C4C - How to trigger BO action each time when standart ALP check box was changed(set or unset)?

[roman_pelykh_23]

Hi Experts,

I have requarement to develop a scenario where I need to set custom check box value of ALP UI elements whenever there is a set/unset in a standart selection check box of the row in ALP. The "List" has the property "SelectOption = multiSelect". In general I have to duplicate the standart selection check box to save its value for the backend.

What I have tried:

Created an action that triggers using Event Handler on "OnLeadSelectionChange" of the data list that binded to UI element List.

Inside the custom action, I have made an logic to set/unset custom field indicator true or false depending on its previous value.

The Problem with my approach :

The script does not trigger each time when standart ALP check box is changed (checked or unchecked).

For example:

I checked 3 rows and script was triggered only for first row.

When I unchecked first row then were triggered script for 2nd and 3d rows and custom check boxes were setted, but for first row script not triggered and standart check box for 3d row was unchecked by itself.

I found thread - https://answers.sap.com/questions/479756/sap-c4c---how-to-trigger-absl-script-when-a-row-is.html

There is solution for "List" with property "SelectOption = singleSelect". I tried there solution but it doesn't work in my case.

Please help me if I am missing something obvious here.

Any help would be appreciated.
