  • Fixes issue where only the last addprop() property would be available
View Release Details

Version 1.15.0

2025-01-18

Multiple Properties Persistence Fix (Corrected)

Fixed critical issue where multiple addprop() calls only persisted the last property. The fix uses builtin() to bypass dynamicprops.subsasgn() override when assigning to DynamicProperties itself.

Key Features:

  • Fixed addprop() to use builtin('subsasgn') instead of direct assignment
  • This bypasses dynamicprops.subsasgn() override when assigning to DynamicProperties
  • Modified dynamicprops.subsasgn() to explicitly handle DynamicProperties assignment
  • Checks if assigning to DynamicProperties itself and delegates to parent immediately
  • Multiple properties added via addprop() now all persist correctly
