Hi @Mohammed8 ,
In Configurable Workspace, a Currency field is rendered as one composite control containing both the amount and currency code.
There is no supported OOB GlideForm, UI Policy, or dictionary configuration to make only the currency-code dropdown read-only while keeping the amount editable.
Using:
g_form.setReadOnly('u_amount', true);
will make the complete Currency field read-only.
Recommended options:
1. If the entire instance must use CHF
Enable single-currency mode:
glide.i18n.single_currency = true
glide.i18n.single_currency.code = CHF
In single-currency mode, the currency appears as a non-editable label.
Important: This setting is instance-wide and affects all currency fields, so do not use it for only one table or field.
2. If only this specific field must use CHF
The cleanest design is:
- Use a Decimal field for the editable amount.
- Use a separate Currency Code field defaulted to CHF.
- Make the Currency Code field read-only.
- Enforce CHF through server-side validation.
3. If you must retain the Currency field
Set its default value to CHF and add a Before Business Rule to prevent users or integrations from saving another currency.
Example:
(function executeRule(current, previous) {
if (current.u_amount.nil())
return;
if (current.u_amount.getCurrencyCode() != 'CHF') {
current.u_amount.setError(
'Only CHF is allowed for this field.'
);
current.setAbortAction(true);
}
})(current, previous);
Replace u_amount with the actual Currency field name.
This protects the data, although the currency dropdown will still remain visible in Workspace.
I would not recommend:
- DOM manipulation
- Disabling the dropdown using querySelector()
- Accessing an internal field such as u_amount.currency_type
- Modifying the OOB Workspace currency component
- Removing currencies from the fx_currency table
Those approaches are unsupported or upgrade-sensitive.
Therefore, for a single field, the best supported solution is a Decimal amount field plus a separate read-only Currency Code field. Use single-currency mode only when CHF must apply across the entire instance.
