Resolving the Html.Glass().GetRenderingParameter<.....> Error in Sitecore 10.4: A Yen Digital Expertise Case Study

In the ever-evolving landscape of digital content management, Sitecore stands out as a powerful and versatile platform. However, even the most robust systems can encounter challenges that require expert intervention. One such challenge is the "Html.Glass().GetRenderingParameter<.....>" error in Sitecore 10.4. At Yen Digital, our team of seasoned professionals tackled this issue head-on, ensuring a seamless experience for our clients. In this blog post, we'll walk you through the problem, our approach to resolving it, and the steps we took to upgrade GlassMapper and fix issues related to Renderings with RenderingParameter Templates.

Understanding the Error

The error "Html.Glass().GetRenderingParameter<.....>" often manifests when there is a disconnect between the GlassMapper ORM layer and the Sitecore rendering parameters. This issue can arise due to various factors, including updates to Sitecore or changes in the underlying data structures. When this error occurs, it can disrupt the normal functioning of your Sitecore instance, leading to performance issues and potential downtime.

What is GlassMapper?

GlassMapper is an open-source object-relational mapping (ORM) framework specifically designed for Sitecore. It simplifies the process of working with Sitecore items by allowing developers to interact with them as strongly-typed objects. GlassMapper translates the Sitecore data into .NET objects, providing a more intuitive and efficient way to manage content.

The Role of Rendering Parameters

Rendering parameters in Sitecore are used to pass additional data to renderings (components) on a page. These parameters allow for greater flexibility and customization of the content displayed. However, when the mapping between these parameters and the underlying Sitecore items is disrupted, errors like "Html.Glass().GetRenderingParameter<.....>" can occur.

The Challenge

Our client, a large enterprise utilizing Sitecore 10.4 for their content management, encountered this error, which impacted their ability to render certain components correctly. The issue was traced back to the GlassMapper code, which needed to be updated to align with the latest changes in Sitecore.

Symptoms of the Error

The "Html.Glass().GetRenderingParameter<.....>" error presented itself through several symptoms:

• Inconsistent rendering of components on various pages.

• Errors logged in the Sitecore diagnostic logs indicating issues with GlassMapper.

• Performance degradation due to failed attempts to retrieve rendering parameters.

Yen Digital's Approach

At Yen Digital, we believe in a systematic approach to problem-solving. Our team of Sitecore experts and developers collaborated to diagnose and resolve the issue efficiently. Here’s how we approached the challenge:

Step 1: Comprehensive Diagnosis

The first step was to conduct a thorough diagnosis of the problem. This involved:

• Log Analysis: Reviewing Sitecore logs to identify the root cause of the error.

• Code Review: Examining the existing GlassMapper code to pinpoint areas of concern.

• Environment Check: Verifying the configurations and settings of the Sitecore environment to ensure compatibility with GlassMapper.

Step 2: Upgrading GlassMapper

Once the diagnosis was complete, it was clear that an upgrade to the GlassMapper code was necessary. The steps involved in this upgrade included:

• Version Compatibility: Ensuring the new version of GlassMapper was compatible with Sitecore 10.4.

• Code Refactoring: Updating the existing GlassMapper code to align with the new version.

• Testing: Conducting extensive testing to ensure that the upgrade did not introduce new issues.

Step 3: Fixing RenderingParameter Issues

The next step was to address the issues related to Renderings with RenderingParameter Templates. This involved:

• Template Analysis: Reviewing the existing RenderingParameter Templates to identify discrepancies.

• Code Adjustments: Modifying the code to correctly handle these templates.

• Validation: Validating the changes through rigorous testing to ensure that rendering parameters were being correctly retrieved and applied.

Step 4: Deployment and Monitoring

After implementing the fixes, the updated code was deployed to the client's Sitecore environment. This phase included:

• Deployment Planning: Ensuring a smooth transition by planning the deployment during off-peak hours.

• Monitoring: Continuously monitoring the environment post-deployment to quickly address any arising issues.

Results and Benefits

The resolution of the "Html.Glass().GetRenderingParameter<.....>" error brought several benefits to our client:

• Improved Performance: The Sitecore instance now runs smoothly, with components rendering correctly and efficiently.

• Enhanced Stability: The updates to GlassMapper and the fixes to RenderingParameter issues have resulted in a more stable environment.

• Future-Proofing: Our proactive approach ensures that the Sitecore environment is better equipped to handle future updates and changes.
