UI Action with mandatory form fields challenge

[Valon Sheremeti]

I have a need to run UI Action on a form which has mandatory fields.

Any best practices are appreciated.

So far this is all I can think of:

-- I can run UI Action with 'Client' checked , (but I need mandatory fields to remain mandatory after UI Action completes)

The way I foresee this process with UI Action is below, but I'm not sure how to call step 3 below

1. Run (client side of UI Action):  g_form.setMandatory(field, false) - this is doable

2. Run (server side of UI Action): gs.addInfoMessage("SSN is:"+ current.variables.ssn.getDecryptedValue()) - this is doable

3. Run - again (client side of UI Action):  g_form.setMandatory(field, true) - this is my challenge - how to call this client script after both client (1) and server (2) scripts are executed.

Sharing other alternatives how to do this are appreciated,

Thank you

Simplifying my own question 🙂

How do I run a UI Action in a form which has mandatory fields (and those fields should remain mandatory after UI Action script completes)? 

Thank you

OK - I figured it out 🙂

So, the following UI Action script will mark required fields as notMandatory, then will execute server-side script and then will reload the form and previously mandatory fields will show up again (as mandatory)

Details below apply to 'Catalog Task'

I hope you will find them helpful

Action Name: display_ssn_and_dob

UI Action needs to have: Client box checked

On Click : nomandatory();

Condition: // you put your own conditions //

Script:

//The following code calls client side part of script

function nomandatory()
{
g_form.checkMandatory = false; //This makes form fields not mandatory
try {

//This code makes catalog task variables not mandatory
var allVariables = document.getElementById('variable_map').getElementsByTagName('item');
for(var i = 0; i < allVariables.length; i++){
var item = allVariables[i];
g_form.setMandatory('variables.' + item.getAttribute('qname').toString(),false);
}
} catch(err) {}

// The following code calls server side part of script
gsftSubmit(null, g_form.getFormElement(), 'display_ssn_and_dob');
}

showpii();

//This is Server side code

function showpii()
{
gs.addInfoMessage("Requester's SSN is: "+ current.variables.reqs_ssn.getDecryptedValue()+". Requester's DOB is:"+ current.variables.reqs_dob.getDecryptedValue());
action.setRedirectURL(current);
}
