How to set Variable from g_modal using UI Action?

miro2 · 3 weeks ago

Hi,

I'm trying to set a variable from g_modal using a UI Action. The goal is to set the value from the button to the variable, but this doesn't work. If I try to save it to any field, then it works properly.

Any thoughts on how to save the value to a variable?
UI Action (client)

function onClick(g_form) {
    var fields = [{
        type: 'choice',
        name: 'reason',
        label: getMessage('Choose reason'),
        value: getMessage(' -- Select -- '),
        choices: [{
            displayValue: 'Missing details',
            value: 'missing_details'
        },
        {
            displayValue: 'Urgent issue',
            value: 'urgent_issue'
        }],
        mandatory: true
    }];

    g_modal.showFields({
        title: "Select your reason",
        fields: fields,
        size: 'lg'
    }).then(function(fieldValues) {
        g_form.setValue('variables.reason', fieldValues.updatedFields[0].value);
        g_form.save();
    });
}

Modal:

Variable editor: empty when reason is seleted

@miro2

this approach will work

1) use GlideAjax in workspace client script and pass the record sysId and the variable value

2) then in script include query that table with sysId and update the variable like this

gr.variables.reason = 'your value';

gr.update():

@Ankur Bawiskar sure, I’ll close this thread since you resolved the first issue with GlideAjax.
Thanks a lot.
