* Fix interactive dialog bugs: dynamic select lookups, radio values, and field refresh
- Cache sanitized fields in AppsForm to preserve object identity across
renders, preventing AsyncSelect from remounting and re-triggering
dynamic select lookups on every keystroke in any field
- Normalize radio field default values to plain strings in getDefaultValue()
so the value shape is consistent with what RadioSetting.onChange returns
(e.target.value). Accept both string and {label, value} object shapes
downstream for backwards compatibility.
- Fix radio field [object Object] in submission by extracting .value from
AppSelectOption objects in convertAppFormValuesToDialogSubmission
- Include selected_field in refresh submission so plugins know which field
triggered the refresh. Use a shallow copy of accumulatedValues to avoid
permanently contaminating the accumulated state.
- Send empty string for cleared select fields in refresh submissions.
Previously, extractPrimitiveValues skipped null values and the spread
merge never overwrote stale accumulated keys.

Mattermost Web App
This folder contains the client code for the Mattermost web app. It's broken up into multiple packages each of which either contains an area of the app (such as playbooks) or shared logic used across other packages (such as the packages located in the platform directory). For anyone who's used to working in the mattermost/mattermost-webapp repo, most of that is now located in channels.
npm Workspaces
To interact with a workspace using npm, such as to add a dependency or run a script, use the --workspace (or --workspaces) flag. This can be done when using built-in npm commands such as npm add or when running scripts. Those commands should be run from this directory.
# Add a dependency to a single package
npm add react --workspace=playbooks
# Build multiple packages
npm run build --workspace=platform/client --workspace=platform/components
# Test all workspaces
npm test --workspaces
# Clean all workspaces that have a clean script defined
npm run clean --workspaces --if-present
To install dependencies for a workspace, simply run npm install from this folder as you would do normally. Most packages' dependencies will be included in the root node_modules, and all packages' dependencies will appear in the package-lock.json. A node_modules will only be created inside a package if one of its dependencies conflicts with that of another package.

Dependency Changes
Any PR that modifies package.json or package-lock.json needs extra scrutiny:
- No duplicate libraries. Before adding a new dependency, check whether an existing one already covers the same use case. Multiple libraries for the same purpose (e.g., two different date pickers, or Bootstrap 3 and Bootstrap 4 simultaneously) create long-term upgrade pain.
- License check. New dependencies must not use GPL or similarly restrictive licenses. Dependencies with no license at all should also be flagged.
- Justify the addition. A new dependency should solve a real problem that existing code or dependencies don't already address. Push back on adding packages for trivial functionality.
- Version conflicts. Check whether the new dependency introduces conflicting peer dependency versions. Cascading version conflicts are expensive to untangle later and have historically blocked upgrades for months.
