How can I write a function that accepts a dynamic number of parameters in a visual rule editor (instead of fixed arguments)?

Hi everyone

I'm working with a visual rule editor (as shown in the screenshot attached – possibly AEM Forms or a similar tool) and I'm trying to create a function like setActionField() that can accept a dynamic number of input values, instead of hardcoding a specific number of arguments (like field1, field2, etc.).

Any guidance or examples would be greatly appreciated!

    Hello @ngọc_duyn633459 

     

    You can refer to doc at [0] for writing the custom functions in AEM Forms and using them through rule editor.

     

    Thanks,

      You can create a custom function and invoke it using a rule. The following documentation provides detailed information about custom functions along with examples:

      Hi @ngọc_duyn633459 ,
      You can try one thing to achieve this, create one text field and set the list of param with the delimiter of :: (or in the form of json) then pass that text field value as a input for your custom method. You can retrieve json and convert as a key value pair / variables as you want.

       

      Thanks.
