TL Views: value-input mit Platzhalter, zugänglicher Name bei verborgenem Label, bedingte Anzeige von Elementen mit visible-if

Design System: Tokens and base classes as own package (wave 0)

#29625

TL Views: a page layout of weighted columns (main 2/3, side 1/3) that reflows to one column on a narrow viewport; the split-panel keeps its sashes and clips the side pane at 400 px

#29629

TL Views: `<show-view>` / `<show-views>` actions reveal a mounted view by name and write its channels from a command chain without a model object

No way to show a master-detail as an overlay: the detail always costs the list half its width

A dashboard tile cannot be the entry point it looks like: neither <tile> nor <card> carries an action

#29550

React controls do not consume the theme's radius and surface tokens consistently; a flat theme needs per-component CSS overrides

#29553

React view <table>: <column> has no width, every column defaults to 150 px, so a table with more than six columns overflows a 940 px pane

TL Views: a URL switches the sidebar away from an item with unsaved changes without asking

TL Views: a warning-level configuration constraint is dropped, so the model editor shows nothing

#29620

TL Views: a tree node is never a link to where its object is displayed, although the display targets declare one

#29622

TL Views: a `<flow-diagram selection="ch">` writes its channel but does not follow it, so a node selected elsewhere is not marked in the diagram

#29623

Build: the translate goal re-translates committed German messages after a pull or branch switch when the doclet did not run in the same build

#29626

TL Views: a panel toolbar has no overflow mode; at 400 px width the ticket page's six commands run 908 px wide, three of them unreachable, and the panel title is pushed out

#29627

TL Views table: an I18NString cell wraps its text and is clipped mid-glyph by the 36 px row instead of ending in an ellipsis; header labels are cut without an ellipsis

#29631

TL Views: Escape closes a <window> dialog while a <start-job> it started is still running; the job runs on with nothing left to show or cancel it

#29634

TL Views: the configuration editor builds a text field for a property whose format is parse-only, so selecting a derived attribute in the model editor fails with "There is no normative way to serialize a locator configuration"

#29635

TL Views: a <tree> renders every node as a link, so a click on the label navigates away instead of just selecting the node

#29639

TL-Script objectResolve(id, typeOrTable): resolution via a type including its subtypes or via a table name, objectTable delivers the table of an object, and an object the current user may not read is not resolved

#29669

A request with a malformed query string ("?q=50%") is answered with an "Internal error" page (HTTP 500) instead of 400

Problem

An address whose query string holds an invalid percent escape, e.g. http://localhost:30049/tl-dev/view/tickets?filter=all&q=50% typed into the browser, is answered with the full "Internal error" page, HTTP 500, and logged as an ERROR:

BadMessageException: 400: Unable to parse URI query
  ... TopLogicServlet.processSessionCheck

The TL Development app, snapshot build 42. The application never generates such an address itself (the view layer encodes %` as `%25); it comes from a hand-edited or truncated link.

Expected

A malformed request is a client error: HTTP 400 with a short page, logged at most as INFO or WARN without a stack trace, not an internal server error. processSessionCheck (or whatever first reads the parameters) catches Jetty's BadMessageException and answers with its status code.

Lösung

TopLogicServlet liest die Request-Parameter jetzt einmal ganz am Anfang der Verarbeitung, vor Cache-Policy und Cookie-Prüfung. Lehnt der Servlet-Container die Parameter ab (Jetty: BadMessageException beim ersten Zugriff), wird die Anfrage mit HTTP 400 und der schlichten Fehlerseite des Containers beantwortet und nur als eine WARN-Zeile ohne Stacktrace protokolliert:

WARN TopLogicServlet - Rejecting request with unparsable parameters '/tl-demo-react/view/': 400: Unable to parse URI query

Das gilt für alle Servlets auf Basis von TopLogicServlet (ViewServlet, ReactServlet, AJAXServlet, TLLayoutServlet, ...), auch für die ohne Cookie-Prüfung. Die Prüfung verwendet keine Jetty-Typen; ein Container, der fehlerhafte Parameter stillschweigend verwirft, besteht sie.
