RowSourceObserver: a disposed observer is still notified and throws NPE (_scope null) from DerivedViewChannel and GlobalModelEventForwarder

#29783

TLScriptFunctions: a script function is bound to an arbitrary overload of the same name, including a private one

#29788

Configuration: the error for an undecodable encrypted property echoes the value (e.g. a plain-text password) into the log

#29789

tl:generate-java fails on the first build after a TopLogic version change: it neither resolves the engine web fragments nor reads the project's own model sources

#29791

TL Views table: the row activation button runs the activation command without selecting its row, so commands reading the selection channel see another row (wrong breadcrumb label)

#29792

TL Views: a closed dialog (and a left tile-stack frame) stays visible for 1 s unless the application ships its own exit animation - move the demo's animations into the engine

#29800

Model patch of an existing database fails when a class gains a generalization and overrides its attributes in the same change

#29806

WrapperGenerator: every top-level class of a module with a singleton extends StructuredElement (regression of #26716)

#29807

WrapperGenerator: classifier constants of two enumerations collide, the generated factory does not compile

#29808

TL Views: the <on-submit> command of a text or number <value-input> runs on Enter only, not when the field is left with a changed value

#29810

TL Views: the selection channel of a <tree> keeps an object deleted in another view, and scripts over it fail

#29813

TL Views: a <tree> does not react to a change of an object it does not display yet, so a node that becomes a child of a shown node does not appear

#29822

CompactHistoryTask: Wartungsfenster bleibt nach dem Lauf aktiv, Task-Ende geht im Neustart der Persistenzschicht verloren

#29824

TL Views table: "Standard wiederherstellen" in the column selection drops a declared group-by (and does not restore the declared sort)

#29837

TestCompileJSPs modifies the module's source webapp and breaks concurrently running scripted tests of the same module

#29838

ClusterManager: a database connection that failed in a cluster transaction is returned to the pool and keeps failing every refetch

#29846

Changing the type of a column with content fails on Oracle (ORA-01439) and of an indexed column on MS SQL Server

#29848

ReportQueueTest.testAddJob fails sporadically: the queue thread may process the job before the test checks that it is queued

#29871

TestZipper.testEmptyFolder fails depending on the order in which the file system lists a folder

#29878

React UI does not react behind a proxy that buffers or refuses the window event stream

TL-Script add() wirft UnsupportedOperationException bei Multi-Referenz auf transientem Objekt

== Beschreibung

Die TL-Script-Funktion add() schlägt mit einer java.lang.UnsupportedOperationException fehl, wenn sie auf ein Multi-Referenz-Attribut eines **transienten Objekts** angewendet wird, dessen Attribut noch leer (nicht initialisiert) ist.

Die von getValue() zurückgegebene Collection für ein leeres Multi-Referenz-Attribut auf einem transienten Objekt ist unveränderlich (z.B. Collections.emptyList()). Add.eval() ruft direkt Collection.add() darauf auf, was fehlschlägt.

== Reproduktion

obj = new(`some.module:SomeType`, transient: true);
obj.add(`some.module:SomeType#multiRef`, $element);
// → UnsupportedOperationException

Dabei ist multiRef ein Referenz-Attribut mit multiple="true".

== Erwartetes Verhalten

add() muss auch dann funktionieren, wenn das Multi-Referenz-Attribut auf einem transienten Objekt noch leer/nicht initialisiert ist. Die Funktion sollte in diesem Fall die unveränderliche Collection durch eine veränderliche ersetzen oder eine neue erzeugen, bevor das Element hinzugefügt wird.

== Stack Trace

com.top_logic.util.error.TopLogicException: Evaluation of 'add($transientAttachments, difa.aema.common:TransienMailAttachments#sendAttachments, $attachment)' failed
    ...
Caused by: java.lang.UnsupportedOperationException
    at java.base/java.util.AbstractCollection.add(AbstractCollection.java:251)
    at com.top_logic.model.search.expr.Add.eval(Add.java:78)

== Betroffene Klasse

com.top_logic.model.search.expr.Add — Zeile 78: Der eval()-Aufruf muss prüfen, ob die Collection veränderlich ist, und ggf. eine mutable Kopie anlegen.

== Workaround

Statt add() kann set() mit concat() verwendet werden:

// Statt:
$obj.add(`Module:Type#multiRef`, $element);

// Workaround:
$obj.set(`Module:Type#multiRef`, concat($obj.get(`Module:Type#multiRef`), list($element)));
