TopLogic Release

2026-07-30

TopLogic 8.0.0-alpha7 introduces the two central innovations of TopLogic 8.0: the React-based UI layer TL Views and model-based access rights.

React UI (TL Views)

Declarative views – views are described in .view.xml files and composed of small UI elements that gain model binding, channels, access control and commands only where needed; they coexist with the classic layout components.
React integration – a new module integrates React controls into TopLogic and delivers state changes to the browser via server-sent events.
Editable tables – tables in forms can be edited row by row.
Conversation display – object lists, file chips and card panels display comment threads.

Security and access rights

Model-based access rights – which roles may perform which operations is defined on types, attributes and modules instead of on views; active by default.
ModelAccessRights API – answers access questions for every access path, including TL-Script, REST interfaces and batch jobs.
Automatic security configurations – possible access configurations are determined automatically.
Re-login on session timeout – "log in again" logs in via SSO instead of redirecting to the login page.

Model and TL-Script

Rich-text descriptions – descriptions of model parts are formatted text shown as tooltips.
Computed default selection – tables, tree tables and grids can compute their default selection by TL-Script.
XML parsing – TL-Script functions based on the declarative XML import.
gzip() – compresses binary values.
Message levels – log() and info() support INFO, WARN and ERROR.
dateFormat() time zone – formats date values losslessly with an explicit time zone.
HTML checks – empty HTML values are recognized correctly.
Variable completion – the TL-Script editor proposes the variables in scope after $.

Configuration and operation

Operation mode – a service provides the application's mode: development, test or production.
Info service messages – appear at the bottom and stay while the mouse is over them.
OpenAPI server rollback – a non-2xx response rolls back the transaction.
Local credentials overlay – the application archetype creates a git-ignored overlay for developer-local secrets.

Bug fixes

Flow diagrams: double clicks, selectable text in PDF exports, sub-grid layouts.
Trees and tables: selection after a refresh, sub-tree selection with level filter.
Persistence: change log during concurrent commits, context-dependent numbering in one transaction, case-sensitive file names of structured texts.
UI: URL routing of the React views, dialogs of invisible components, image drop field, tooltips of main tabs.

Migration

TL Views and the React module.
Model-based access rights and automatically determined security configurations.
Rich-text model descriptions, dateFormat() time zone, operation mode service.
Default logging configuration, sequence identifiers of resetSequence/generateSequenceId, database definition of tags, multi-valued references to deleted objects, flow diagram sub-grids.

Details are given in the migration section of the release notes below.

#29384

The TL-Script functions `resetSequence` and `generateSequenceId` generate a different sequence ID than `SequenceDefaultProvider` (in terms of suffix and context order), so they cannot reset a provider-managed sequence with a dynamic context
