The ContextHub is AEM’s framework for contextual data and personalization. Using a geo-location store within ContextHub allows you to capture the visitor’s location and then use that data in personalization rules for components on a single page. This is more efficient and maintainable than creating entirely separate pages (MSM) or manual authoring, as it centralizes logic and content on one page structure.

Dialog performance is often impacted by loading many complex widgets (like rich text editors and path browsers) simultaneously. The best practice is to structure the dialog so that non-essential or dependent fields are only loaded when required (e.g., using `granite:ui/include` or showing fields based on the value of another field). This reduces the initial payload and processing time.

Hard-coding absolute paths makes components fragile and non-portable. If the content is moved or the site structure changes, these links will break. The correct approach is to leverage AEM’s resource resolution, using relative paths, the `PageManager`, or Sling’s resource APIs to resolve assets and pages dynamically. This ensures links remain valid across different environments and after content restructuring.

This is a classic symptom of a component being part of a Live Copy relationship where inheritance (rollout) is still active. When the component is on a page that is the source (blueprint) for many Live Copies, editing it can trigger a rollout, propagating the change to all related Live Copy pages. The solution is to suspend inheritance or cancel inheritance for that component on the specific pages where unique content is needed.

For querying pages or assets based on properties, the QueryBuilder API is the recommended, robust service in AEM. It provides a higher-level, more secure abstraction over JCR queries, handles escaping, and is easier to parameterize. It’s important to apply strict limits (like `p.limit=-5`) and efficient property filters to ensure the query is performant. Direct SQL2 or manual traversal are typically less maintainable and can be error-prone.

The core requirement—checking a dynamic condition (download count)—requires custom logic. A Process Step is designed to execute server-side code (ECMAScript or Java). This code can access the asset’s metadata (where the download count might be stored or calculated) and then decide whether to proceed down a path that triggers the email. OR Splits only evaluate simple workflow metadata, not complex external data.

In the modern, editable template architecture, policies (which define allowed components) are managed at the template level. To create a variation of an existing template with a different policy, the correct approach is to create a new template that inherits from the original via `sling:resourceSuperType`. You can then edit the policy for the new template without affecting pages created from the original template. Modifying the original template’s policy would affect all existing pages.

The primary concern with custom servlets, especially those on open paths like `/bin`, is improper authorization. If the servlet does not enforce sufficient access controls (e.g., by checking user privileges or resource permissions), it can become an information disclosure vulnerability, allowing unauthorized users to access data by hitting the endpoint directly. While using `/apps` is a best practice, the lack of ACLs is the core security flaw.

AEM’s Manage Publication wizard (accessed via the Sites console or page properties) provides built-in scheduling functionality. It allows authors to set specific ‘On Time’ and ‘Off Time’ for a page or asset. The system then uses a background process to automatically trigger activation and deactivation at the specified times, which is the standard, out-of-the-box way to handle this business requirement.
