How to capture a field value in scratchpad within UI Action?

[Zod]

Hi Experts,

please tell me how I can 'catch" a field value in an UI Action within a scratchpad variable to be able to check for it within an Workflow that is triggered by the UI Action.

I was assuming something like "g_scratchpad.u_field = current.u_field;"   would work ... but it doesn't.

Thank you.

g_scratchpad is used in client-side scripting.

It is unclear how you intend to use this within a Workflow

[Zod]

The use case is, that the UI action will change a field value that will trigger a workflow that includes an approval.

The UI action can run on 2 possible values of the field ... so in case of rejection, I would like to use the scratchpad to provide information about the field value of the moment, the UI action was triggerred (before the value changed) ... so that I can change back to that value.

I guess it may be wrong.

scratchpad variable will bring the data from server to client.

Is your UI action contains client side and server side functionalities,

If then g_scratchpad_name = g_form.getValue('name');

var name1 = g_scratchpad_name;

server side function

executeFunction(name1);

send it as some parameter based function

[Zod]

//UI Action

function clickedRRR(){

  if(confirm('Sure?')){  

  gsftSubmit(null, g_form.getFormElement(), 'action_name');

  }

  return false;

}

// Server side code

if(typeof window == 'undefined')

  myFunction();

function myFunction(){

  // catch old u_field value in scratchpad

  g_scratchpad_u_field = g_form.getValue('u_field');     // THIS IS WHAT YOU MEAN?

  current.u_field= 'abc';     // Workflow waits for abc to start

  current.update();

  gs.addInfoMessage(gs.getMessage("Message"));

}
