WebViewer Core

New

General

• Improved styling behavior for both iframe and WebComponent integrations by shipping styles as standard CSS stylesheets.

Office Editor

• Added column APIs for building layout to OfficeEditorDocument.

Spreadsheet Editor

• Added support for custom HTTP headers when loading spreadsheet documents, enabling authentication and special header requirements.

Tools

• Added setMeasurementLabelsHandler API to ArcMeasurementCreateTool, allowing users to customize labels that are applied to newly created Arc Annotations.

Fixes

Annotations

• Fixed line endings to better match the Core SDK and Adobe.

• Fixed an issue where Perimeter Measurement annotations could have a NaN angle in the Measurement Details.

• Fixed an issue where AnnotationChangedSources was not exposed correctly.

• Fixed an issue where Arc Measurement annotations only had English labels in the comment panel.

• Fixed an issue where dragging annotations across pages with replies with different authors would set the author as the current user.

Arrow Key Page Navigation

• Fixed an issue where page navigation with arrow keys would take precedence over input box cursor navigation.

Copy and Paste

• Fixed an issue where when copying text with certain RTL characters and pasting text would paste the wrong text.

Date Picker

• Fixed an issue where date tokens in date formats were interpreted incorrectly with the date picker widget.

Form Fields

• Fixed an issue where font sizes in form field create tool preview elements were not updating when the zoom level changed in FormBuilder mode.

• Fixed an issue where programmatically setting tool mode would be overridden when tools with lifecycle methods triggered additional tool changes during switchIn, ensuring tool mode changes are properly preserved and not overwritten by subsequent lifecycle callbacks.

Measurement

• Fixed cloudy measurement annotations missing an appearance, which made captions disappear.

Office Editor

• Fixed an issue where text highlight was rendered incorrectly after zooming.

• Fixed an issue where getSelectedText returned an empty string in Office Editor.

• Fixed issues caused by default query parameters when loading office editor worker.

• Fixed an issue with Korean IMEs where arrow keys could cause characters to be duplicated or deleted.

Page Navigation

• Fixed an issue where arrow keys would trigger page navigation if enabled while editing annotations.

RTL

• Fixed an issue where changing the display mode of an RTL document would not render the pages in the right order.

Tools

• Fixed an issue where the text selection toggle flag was on all tool instance classes. They are now instance methods on instances of TextTool, and won't be static to all tools.

MultiViewer

• Added APIs: getActiveDocumentViewerKey() and setActiveDocumentViewerKey(key) for querying and updating the active document viewer in Multi-Viewer Mode.
