13.33.0

Release date 17-06-2026

New Features

• Load a zaak in a form flow

  A new zakenFormFlow bean lets form flows load a zaak from the Zaken API by its identificatie through a getZaak method that can be used in SpEL expressions (for example onOpen or onComplete). The full zaak is returned, so any of its fields can be used in subsequent steps or conditions. Access is secured with PBAC: a new Zaak resource type with a view action ensures only users authorized for the matching zaaktype can load a zaak. See Load a zaak in a form flow for details.

Enhancements

• Configurable modal size for start forms

  The process link configuration of a start event now offers the Modal size option (Extra small, Small, Medium, Large). When a case is created via the Start case button, the start form modal opens in the configured size instead of always being small. If multiple processes can create the case, the modal opens in the size configured for the selected process. When no size is configured the modal keeps its previous default.

• Value resolver support for Besluiten API plugin date fields

  In the Besluiten API plugin, the create besluit action can now resolve the publication date, shipment date and response deadline from a value resolver expression (e.g. pv:publicatiedatum or doc:/besluit/publicatiedatum) instead of only a fixed date, selectable per field via an input-type toggle.

• Building blocks support nested document properties

  Input and output mappings on building block call activities can now reference nested paths in the case or building block document (e.g. /person/name), instead of only top-level properties.

• Selectable widget layout algorithm

  The algorithm used to arrange widgets can now be chosen per case widget tab, IKO tab and dashboard. Three options are available:

  • Default (less gaps) (MUURI_GAP_FREE) — Muuri masonry with gap filling. This is the original behaviour and is used when nothing is configured, so existing configurations are unaffected.

  • Default (MUURI) — plain Muuri masonry without gap filling.

  • Gap free (BEAUTIFUL) — a new custom dense-packing algorithm that may reorder widgets within a section to remove gaps, almost always producing a clean layout without holes.

  Default and Default (less gaps) keep the widgets in their configured order as much as possible but can leave empty space, while Gap free reorders widgets to eliminate gaps. The choice can be made in the admin UI (the dashboard edit modal, the case Edit widget tab modal and the IKO tab modal) and via auto-deployment through the optional widgetLayout property on the dashboard, case widget tab and IKO tab definitions. See the dashboard, case widget tab and IKO tab documentation for details.

Bugfixes

• Empty building block mapping dropdowns

  Existing input and output mappings on a building block process link sometimes showed up with empty dropdowns. This has been fixed.

• Keycloak-based database migrations failed against newer Keycloak servers

  Database migrations that look up users in Keycloak could fail to start when running against a newer Keycloak version than the one Valtimo ships with. This has been resolved.

• Misleading plugin configuration error when configuring a building block call activity

  When a call activity to a building block was missing the required business key configuration, saving the process link failed with a confusing "No plugin configuration mapping provided" message. Valtimo now checks the call activity up front and shows a clear error that points to the missing business key configuration.

Security

• Spring Boot upgraded for CVE fixes

  Upgraded Spring Boot to 3.5.15 to resolve several HIGH-severity CVEs.
