Then, inside your handler, get the SObject record and pass it through Salesforce’s Formula.recalculateFormulas method.
| Code Block |
|---|
// do this inside the handleEvent method of your handler class:
B25.FormRecord theFormRecord = form.getActiveRecord();
SObject theSObjectClone = theFormRecord .getSObjectClone();
Formula.recalculateFormulas(new List<SObject>{theSObjectClone}); |
Finally, get the new value for the formula field and let the form update it by using the put method of B25.FormRecord.
| Code Block |
|---|
// still inside the handleEvent method of your handler class:
String theNewValue = theSObjectClone.My_Formula__c;
theFormRecord.put(B25__Reservation__c.My_Formula__c, theNewValue); |
Important to note is that although the put method can update formula field values displayed on the form, subsequent calls to get or getSObjectClone will not contain the updated value in the field, as illustrated here:
| Code Block |
|---|
B25.FormRecord theFormRecord = form.getActiveRecord(); SObject theSObjectClone = theFormRecord.getSObjectClone(); theFormRecord.get(B25__Reservation__c.My_Formula__c); // returns the OLD value theSObjectClone.get(B25__Reservation__c.My_Formula__c); // returns the OLD value Formula.recalculateFormulas(new List<SObject>{theSObjectClone}); theFormRecord.get(B25__Reservation__c.My_Formula__c); // returns the OLD value theSObjectClone.get(B25__Reservation__c.My_Formula__c); // returns the NEW value theSObjectClone = theFormRecord.getSObjectClone(); theSObjectClone.get(B25__Reservation__c.My_Formula__c); // returns the OLD value |
