Popup clears definition expression on Feature Layer

DiegoDíazDoce

Hello,

I'm hoping that someone can tell me whether this is the expected behaviour in Experience Builder:

1. I have a map widget (widget1) that points at a webmap
2. I also have a second widget (widget2) that uses the MapViewManager to access the JimuMapView instance from widget1.
3. From that instance, it gets access to one of the webmap feature layers (JimuMapView.MapView.Map.Layers) and sets a definition expression on it
4. The feature layer is then filtered on the map according to the definition expression as expected.
5. However, when you click on the map and a popup displays, the definition expression is automatically cleared (I checked the definition expression value before and after displaying the popup) and the feature layer displays again all features, making setting the definition expression directly on the feature layer not viable in Experience Builder.

Thanks in advance for your help

Have you tried setting a filter in your webmap? If you want to hide something and never unhide it, it is a simple solution.

From your description, this sounds like an issue where React is triggering a re-rendering of some component that is removing your definition expression. There is probably a way to write a useEffect hook that watches your definition expression and re-adds it if it is removed, but it will be tricky to find the right way to do it without triggering an infinite loop.
