Issue with Split Event Widget in Experience Builder – EventOID Not Detected

[AlexandreMatveev]

Hi everyone,

I'm working with an LRS and trying to use the Split Event widget in ArcGIS Experience Builder (ArcGIS Online, latest version), but I'm running into an issue. Here's what I've done so far:

What I’ve Done:

• Published an LRS as both a Map Image Layer and a Feature Service.
• Verified that the Split Event tool works in ArcGIS Pro—it successfully splits events from the published LRS.
• Created a Web Map that includes both the Map Image Layer and Feature Service.
• Built an Experience Builder app with two widgets:
  • Map Widget: contains the Web Map.
  • Split Event Widget: configured to load all events from both the Map Image Layer and Feature Layer (duplicated for testing purposes).

Expected Behavior:

• The Split Event widget should allow me to select a linear event and split it.

Actual Result:

• The widget detects the measure of the selected event but does not detect the Event OID.
  
• As a result, the Split button remains inactive and the tool cannot be executed.

My Questions:

1. Is there a known issue with the Split Event widget not recognizing Event OIDs in Experience Builder?
2. Are there specific configuration steps or requirements for the Web Map or services to ensure compatibility?
3. Should I be using only the Map Image Layer or the Feature Layer—or both?
4. Is there a workaround or best practice to make this widget function as expected?

Any help or guidance would be greatly appreciated!

Thanks in advance,

@AlexandreMatveev The requirements and configuration steps are documented at:

Use the feature service in your webmap.

I believe I’ve found the solution on my own.

Initially, my web map included a Map Image layer and only one Event Feature service, which I intended to split. However, I discovered that the widget also requires a Network Feature service in addition to the Event Feature service.

Once I added the Network Feature service, the widget began detecting the Event OID correctly.
