Add value verification and retries when filling forms

[mVermaat]

In some edge cases it can happen that a value isn't set properly. This usually happens if fields are being set fast. In example

Property	Value
Product	TestProduct
Price	100

Using the follow table as values for a record and there is client side functionality that defaults the price of the product. What sometimes happens now is that while the software tries to write 100, the default price 50 is set. This causes the end result of 50100.
