+#  EditActionHasUniqueTask
+
+> [!CAUTION]
+> Not released, just a specification
+
+- The purpose is to make any task for an action with the preset `edit` to be unique :
+  - If offline, an edit could be in pending task
+  - If launch a new edit, instead of creating a new task, the one in pending task will be opened
+    - so data already filled will be displayed
+    - and when validating, just register new data, waiting to network to come back
+
+# Setting to activate the feature

+##  MobileProject
+
+> 🚧 how to inject inside mobile app for new projet? (have a boolean inside mobileapp file, and "4d mobile app" + android project generator must do the following edit
+
+##  Android
+
+Inside `app/src/main/assets/appInfo.json`
+
+```json
+	"action.edit.hasUniqueTask": true
+```
+
+##  iOS
+
+Inside `Settings/Settings.plist`
+
+```xml
+	<key>action.edit.hasUniqueTask</key>
+	<true/>
+```
+
+## If we want to go further
+
+> :bulb: We could imagine have some definition by action, not only "edit" one. For that for instance a new boolean `hasUniqueTask` could be in the future added to the action json (or if we have time)
+
+### for iOS
+
+in storyboards definition inside `userDefinedRuntimeAttribute`
+
+### for android
+
+Inside `app/src/main/assets/actions.json` by action
