8.0.0-alpha12

TopLogic Release

2026-10-30

TopLogic 8.0.0-alpha12 moves the engine to Java 21, completes the move of the React UI to the design system package, and brings action chains with named arguments, a consolidated access check for views and commands, and a new project setup without a TopLogic parent POM. The AI modules are now part of the engine.

Platform and build

• Java 21: the engine is built for and runs on Java 21; Jetty moves to the EE 11 environment.
• Projects without parent POM: applications and fragments can import the BOM tl-bom, use the packagings tl-app / tl-fragment of tl-maven-plugin and pick features through the starters tl-starter-*.
• Archetype with React UI: tl-archetype-app creates a React application by default; the option ui selects react, classic or both.
• AI modules in the engine: tl-ai-* and tl-chat* are engine modules and are released with the engine version.
• Build checks: JavaDoc references and unused imports are checked in the Maven build; a Git merge driver for the generated resource bundles avoids conflicts between parallel branches.

React UI (TL Views)

• Design system completed: all remaining controls (inputs, media, calendar, kanban, dashboard, editors) draw with the design system package; tlReactControls.css is removed.
• Action chains with named arguments: triggers deliver several named values, scripts use them as variables without a lambda head, and follow-up actions of an action with a result go into <with-result>.
• Forms: actions <enter-edit-mode/> / <leave-edit-mode/>, normalization of entered values, insertion suggestions computed by TL-Script, mentions (@/#) in the HTML editor, a select field that also takes a free value, multi-valued binary values as file chips with multi-upload (<file-list> is removed).
• Tables and trees: <tree-table> with Excel export, node display and row-class; unsortable columns; filter presets with counter and CSS class; faster row selection.
• Further elements: floating action button and speed dial, multi-selection in flow-diagram, slider ranges and time input with seconds from channels, select options in list order, browser tab title following the shown view.
• Tile stack navigation: <frame> declarations carry an id and are nested; <navigate-push> and display targets address a frame.
• Service configuration: the service configuration can be viewed, edited and saved in the React UI, marked "restart required".
• Windows follow foreign commits: commits of other threads reach every window without configuration.

Security and access rights

• One access check definition: views, commands and TL-Script functions declare access checks the same way, as operations on the type of the shown object; custom operations are declared on the type.
• Discover right: model based security knows a right to discover an object (filtered object sources, masked form fields).
• Initial groups: every application gets the groups user (default group of new accounts) and superuser with matching roles.
• Credentials without secrets in the configuration: named secret sources, token based authentication (Keycloak/OIDC, workload identity, Azure) and an API gateway.

Configuration and operation

• Input fields by annotation: configuration forms choose their editors through domain annotations (@MultiLine, @Code, @Html, @Inline, …), equally in the classic and the React UI; @ControlProvider and @ConfigControl are removed.
• Startup hooks: configurable hooks run after all services have started and replace several setup modules.
• Configuration references: config:ref addresses an entry of a keyed list by a globally unique key; a view overlay addresses every element by its id.
• JSON Schema: typed configurations can be serialized against a generated JSON Schema 2020-12.
• XML import: reporting of unknown elements, <set-translation>, <unless-known> and a partial <resolve-existing> for evolving external formats.
• AI: LLM providers can be enabled through environment variables only; the model catalog has a view of its own.
• Mail server daemon: new mails are recognized by their IMAP UID; unknown mails stay in the inbox by default.
• Persistency: faster deletion on H2 and a single-branch configuration for applications without branches.

Bug fixes

• React UI: table rendering after reload and with large filtered row sets, panel heights in split panes, tabs and stacks, split-panel sizes in px, tab strips wider than their container, navigation targets painted without their selection, login logging out immediately.
• Security and model: derived attributes for users without Discover right, enumeration values not discoverable for non-administrators, groups and addresses not readable for superusers.
• Performance: quadratic set building, module lookup in TLModelUtil, memory kept by windows without SSE connection.
• Migration and build: application module migrations without stored version, update-class into another module, several unstable tests.

Migration

This release requires changes in applications: Java 21 for build and runtime, stylesheets addressing the removed tl* CSS classes of the React controls, scripts and actions in .view.xml files (named arguments, <with-result>, unique ids, tile stack frames), access checks of views and commands, the removed annotations @ControlProvider / @ConfigControl, setup modules replaced by startup hooks, secret configuration and the mail server daemon. The migration section of the release notes describes each step.
