Formula Guards Implementation (Dynaforms)

Achievements & Changes

• Implemented Hard Guards for Field Type Changes:
  • Modified RightPanelStaticComponent.onNumberTypeChange to block changes to/from Percentage or Currency if the field is referenced in formulas, rules, or validation.
  • Added RightPanelStaticComponent.onCurrencyChange to block currency code changes (e.g., INR to USD) for fields used in formulas.
  • Used cdr.detectChanges() to revert UI state visually when a change is blocked.
• Enhanced Property Panel UI:
  • Updated right-panel-static.component.html to bind the Currency dropdown to the new guard method.

Decisions

• Blocking vs Warning: Decided to use a hard block (Error Toast) instead of a warning for currency/percentage changes to prevent silent data interpretation failures.

Dynamic Formula Output Types (Dynaforms)

Achievements & Changes

• Implemented Runtime Output Type Switching:
  • Updated form-element-config.types.ts to store outputType and outputCurrency per FormulaDefinition.
  • Modified RightPanelStaticComponent to bridge inferred output types into library entries.
  • Updated FormulaFieldComponent (Renderer) to detect active formula types and hot-switch between p-datepicker and p-inputNumber.
• Edge Case Mitigation:
  • Implemented automatic value clearing (setValue(null)) when the output type switches at runtime.
• Bug Fixes (PM Update):
  • Race Condition: Swapped emission order in FormulaBuilderComponent to ensure outputType is persistent before a save.
  • Chained Inference: Enhanced suggestion mapping so formulas identify as Dates or Currency when referenced in other formulas.

Decisions

• Immediate Value Reset: Critical for stability when switching between DatePicker and InputNumber.
• Emission Ordering: Discovered that saving a formula must happen after the type assertion to ensure state consistency.
