Implementation Complete: Add Flag to Always Lazy Load a Component

Successfully implemented support for a lazy = true flag on CBWIRE components that enforces lazy loading by default, with full override capabilities using lazy=false in wire() calls.

✅ All Requirements Implemented

  1. Component Declaration: Components can declare lazy = true to be always lazy loaded
  2. Default Lazy Loading: Components with lazy = true are lazy loaded by default
  3. Override Capability: lazy=false in wire() calls overrides component's lazy preference
  4. Child Component Support: Child components with lazy = true also respect the lazy flag

✅ Implementation Summary

Files Modified:

  • models/Component.cfc: Updated lazy loading logic for both main components and child components
  • models/CBWIREController.cfc: Modified wire() method to respect component lazy preferences
  • test-harness/tests/specs/CBWIRESpec.cfc: Added comprehensive test suite and updated existing tests
  • test-harness/views/lazy-demo.cfm: Demo page with proper CFML pound sign escaping

Test Components Created:

  • TestAlwaysLazyComponent.cfc: Component with lazy = true
  • TestParentWithLazyChild.cfc: Parent component using lazy child
  • TestParentWithOverride.cfc: Parent overriding child's lazy setting

Test Coverage:

  • Component with lazy = true loads lazily by default
  • Override behavior with explicit lazy=false
  • Child components with lazy = true are lazy loaded
  • Parent components can override child lazy preferences
  • Explicit lazy=true parameter works correctly
  • Updated existing tests to use lazy instead of lazyLoad

✅ Key Features

  1. Minimal Implementation: All changes build on existing patterns, no breaking changes
  2. Consistent Behavior: Both CBWIREController.wire() and Component.wire() use same logic
  3. Full Override Support: Explicit parameters always take precedence over component preferences
  4. Comprehensive Testing: All scenarios covered with automated tests
  5. Clean API: Only supports lazy = true/false property as requested
  6. Proper CFML Syntax: Demo page uses correct pound sign escaping

Usage Examples

// Component with always lazy loading
component extends="cbwire.models.Component" {
    lazy = true;  // This component will always be lazy loaded by default
    // ...
}
<!-- Default behavior: lazy loaded due to component's lazy = true -->
#wire( name="UserActivity" )#

<!-- Override to force immediate rendering -->
#wire( name="UserActivity", lazy=false )#

The implementation is complete, tested, and ready for production use!

Original prompt

This section details on the original issue you should resolve

<issue_title>Add flag to always lazy load a component</issue_title>
<issue_description>Always Lazy Loading
To enforce that a CBWIRE component is always lazy-loaded, you can add lazy=true to the component class:

// ./wires/UserActivity.cfc
component extends="cbwire.models.Component" {
    lazy = true;
    // Other component methods...
}

If you want to override this default lazy-loading behavior, set the lazy parameter to false:

#wire( name="UserActivity", lazy=false )#
```</issue_description>

@copilot I don't want lazyLoad = true/false, just lazy = true/false on the component.

Updated to only support lazy = true/false property on components. Removed the lazyLoad property support entirely and updated existing tests to use the new lazy property. Changes made in commit e0fb55f.
