Real time evaluation of formula fields on Visualforce pages
Development (Apex, LWC & VF)
To use a formula field in a Visualforce page you have two options.
1) Perform a DML operation on the object and then re-query the object. In many cases this is not a good design or just won't work based on the requirements.
2)Create a wrapper class for the object with get methods that calculate the value of the formula field. This is no fun and can end up being a lot of extra work to get the value for one field. It also adds another layer of complexity if you need to make changes to this formula field, UI vs code deployment.
It will be a wonderful day when you can simply rerender the field and the formula will update.
