Map Viewer Web Form - incremental number updates when the feature is moved

PanGIS — Mon, 26 Aug 2024 10:16:46 GMT

Hello!

I have a web form that calculates an incremental ID and then concatenates it to form a refNumber.

It works fine until you decide to update the point: let's say the position is incorrect and you need to move it.

this is the code and below are the results: the number should stay the same as it is the same point:

// Get the current feature's newID field value var currentID = $feature.newID; // Check if currentID is null or empty, meaning this feature needs a new ID if (IsEmpty(currentID)) { // Get the maximum value of the newID field from all features in layerName var maxID = Max(FeatureSetByName($datastore, "layerName", ["newID"]), "newID"); return maxID + 1; } else { // If currentID is already set, return the existing currentID return currentID; }

create a point with ID 5 and then moved it becomes 6

Any idea?

Thanks!

Think you just need to check the $editcontext.editType. If "INSERT", calculate ID, if "UPDATE", just move point without calculating.

Basically the same as this post.
