Description

The guided loan product wizard's Delinquency Bucket select (editable in Two Wheeler, Education, Agriculture, BNPL, Credit Card EMI, Home, Mortgage, Gold, Auto, JLG, Consumer Durable and LAS) offered two hardcoded options — 'Bucket 1 – Standard' and 'Bucket 2 – Aggressive' — with guessed ids that name no real bucket on any tenant. Classic sources this list from loanProductsTemplate.delinquencyBucketOptions.

Selecting either fabricated option attached whichever bucket actually holds id 1 or 2 on the tenant — a different delinquency classification than the label promised — or produced a raw 400 if no such bucket existed at all.

Fixed by wiring delinquencyBucketId into the existing TEMPLATE_OPTION_SOURCES mechanism (the same one the currency field already uses), with a small shape hook since delinquencyBucketOptions is keyed id/name rather than id/value. The "None" choice stays a static option — it's the wizard's equivalent of Classic's clear button, not a bucket, so it has no template counterpart and needs to survive a template-less render; it now also resets enableInstallmentLevelDelinquency, matching Classic's clearProperty.

Summary by CodeRabbit

  • New Features

    • Custom and Advanced loan product profiles now support Classic Details, Currency, Terms, Settings, and Preview steps.
    • Advanced payment strategy selections populate deferred income recognition from the tenant template.
    • Loan product settings display delinquency buckets provided by the tenant template.
    • Added a clear “None” option; selections use backend-issued IDs.
  • Bug Fixes

    • Selecting “None” clears the bucket and disables installment-level delinquency.
    • Added fallback behavior showing only “None” when no buckets are available.

Walkthrough

The loan product wizard now supports hosted Classic steps for Custom/Advanced profiles. It mirrors Classic form controls, derives advanced-payment state, assembles Classic review and submission data, and loads delinquency bucket options from the tenant template.

The wizard assembles Classic preview and review data, applies payload fixups, validates hosted forms, and submits Classic data. Tests cover tenant bucket selection, None normalization, and deferred income recognition.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to a8b05

The wizard now uses tenant-defined delinquency buckets instead of fabricated options and keeps the None choice as a clear action. No actionable merge-blocking risk remains; the remaining follow-ups are localized code-quality and test-maintenance improvements.

Seed delinquencyBucketId from the template bucket. When loanProductsTemplate contains { delinquencyBucket: { id: 7 } }, syncTemplateDefaults() keeps the control at '' because it reads only delinquencyBucketId. buildPayload() then sends null and forces enableInstallmentLevelDelinquency to false. Use delinquencyBucket?.id ?? delinquencyBucketId and add a regression test for id 7.

Extract the shared deferred-income seeding.

This body duplicates syncDeferredIncomeRecognition at lines 1342-1360. Only the source of the two enable flags differs. Both copies read the same six template option keys, so a template contract change must be applied twice.

Extract one private helper that accepts enableIncomeCapitalization and enableBuyDownFee and builds the DeferredIncomeRecognition object. Both callers then pass their own flags.

Match the Advanced Configuration step by identifier, not by title.

This condition compares step.title against the display string 'Advanced Configuration'. If the title is renamed or localized, the condition stops matching and the step reappears for Custom/Advanced. The hosted Classic Settings step already owns those Event Settings fields, so the operator would then see two copies of the same controls.

Give the step a stable discriminator, for example a FormStepKind value or its id, and match on that.

This test duplicates the previous one and does not check a payload.

The arrange block, the action, and both assertions are identical to the test at lines 452-475. The name promises a "Classic-equivalent payload", but the test never calls buildPayloadForSubmit and never inspects a payload. It therefore adds no coverage and reports a false signal about payload parity.

Either delete this test, because the test at lines 623-658 already covers Classic payload assembly, or extend it to assert the deferred-income keys on buildPayloadForSubmit().

♻️ Proposed change: assert the payload instead of repeating the previous assertions
     component.onClassicAdvancePaymentStrategy(LoanProducts.ADVANCED_PAYMENT_ALLOCATION_STRATEGY);
 
-    expect(component.deferredIncomeRecognition?.capitalizedIncome?.enableIncomeCapitalization).toBe(true);
-    expect(component.deferredIncomeRecognition?.capitalizedIncome?.capitalizedIncomeCalculationType).toEqual({
-      id: 'FLAT'
-    });
+    const payload = component.buildPayloadForSubmit();
+
+    expect(payload.enableIncomeCapitalization).toBe(true);
+    expect(payload.capitalizedIncomeCalculationType).toEqual({ id: 'FLAT' });
   });
