A Suitable Replacement for the Deprecated setFieldValue() Method in Guidewire

In today's fast-evolving tech landscape, maintaining compliance with best practices and industry standards is crucial. One common issue faced by developers working with Guidewire is the deprecated setFieldValue() methods, which have been flagged for violation under Cloud Standards. This post aims to uncover the reasoning behind this deprecation and offers suitable replacements to avoid Cloud Assurance violations.

Understanding the Problem

The setFieldValue() methods have been defined in the com.guidewire.pl.persistence.core.BeanMethods interface and have several implementation classes. However, they are not just deprecated; they are also found in hidden packages that are not compliant with Guidewire Cloud Standards. This presents a significant challenge for developers who want to set field values but must steer clear of these methods.

The Risks of Using setFieldValue()

Data Integrity: The use of reflective methods such as setFieldValue() can bypass built-in validations. This can lead to unintended data corruption, especially in critical areas such as financial data.

Brittle Code: The reliance on hardcoded strings for field names can cause maintenance challenges and technical debt.

Production Issues: The method has been linked to severe problems in production systems across various xCenters, leading to significant operational challenges and errors.

Transitioning to Alternatives

To switch from deprecated methods, it is essential to consider the state of the entity or object in question. Here are key considerations and alternatives:

1. Understanding the State of the Entity

Before attempting to set values directly, ask yourself the following questions:

Why are standard getter and setter properties not available?

Is there a special process that you need to follow to change these values?

Are there validations that need to be in place before making changes?

Could changing these values potentially create more issues?

2. Suitable Alternatives

Depending on what you are working with, different solutions apply:

If the Object is an Entity/Bean

Setting an Attribute/Field Value:
Instead of utilizing setFieldValue() to set an attribute, use the dedicated set() function from the non-instance entity class.

Example:

Setting the Entire Object by Key:
There may not be a direct replacement for setting a whole object by its key, and in this case, you might need to continue using setFieldValue() pending approval from your Cloud Assurance contact.

Example:

If the Object is Not a Database-Backed Entity/Bean

If you are dealing with objects that are not bound to a database, the standard does not apply, and you typically won’t need a replacement. However, reach out to your Cloud Assurance contact for confirmation.

Example:

For Scheduled Items

When dealing with scheduled items, it is advisable to utilize PropertyInfos and ValueProviders for accessing values rather than directly manipulating columns.

Conclusion

Navigating the deprecation of setFieldValue() methods is essential for any developer working with Guidewire to ensure data integrity and compliance with Cloud Standards. By understanding the reasons behind this change and adopting the alternatives laid out in this guide, developers can effectively transition away from deprecated methods while upholding system standards.

Remember to discuss any uncertainties with your Cloud Assurance contact to receive the guidance needed for compliance and best practices.
